Core system

HIPE

Editors & Views

  • Files ending with extension ".csv" are recognized as tables, and opened as such with double click in the Navigator view or with File > Open.
  • The tooltip shown when the mouse cursor is over a task in the Task view is now more informative.
  • Autocompletion in the Console has been improved.
  • A variable value can be copied by right clicking on the variable in the Variables view and selecting Copy value; it can be pasted in the Console or Jython editor afterwards. This works only for strings and numbers.
  • Drag & drop a variable from the Variables view to the Console writes the variable name. The same behaviour can be achieved when dropping it to a Jython editor.
  • Drag & drop selected text from a Jython editor to the Console or vice-versa copy & paste that text.
  • The small level-2 preview shown in the top-right corner of the Observation Context viewer can be enlarged by just clicking on it.

Startup & Shutdown

If the running Java platform is not supported, a warning is popped up.

Feedback

A feedback button has been added for documentation and HIPE functionality.

Look & Feel

Aqua look & feel has been replaced in Mac OS X by the HIPE look & feel that is used among all platforms.

Plug-ins

HIPE now supports plug-ins, with are small packages that anyone can easily create and distribute to share code (Java or Jython) and data (LocalStores). Plug-ins can be downloaded and installed with a single-click.

Plotting

  • Title and label can accept LaTeX commands \textrm \textit \textbf \mathrm \mathit \mathbf. for example, V$_{\textrm{LSR}}$

TablePlotter

OverPlotter

Dataset viewer

Astronomical utilities

  • RadialVelocity now uses TimeCorrProduct to select pointing data
  • SSO now uses TimeCorrProduct to select pointing data
  • Improved documentation

Numeric routines

Data fitting

  • A complete new GUI for the SpectrumFitter is added. Start it from the SpectrumExplorer right mouse menu, select SpectrumFitterGUI. Besides the functionality that was available in the SpectrumFitterTool, the GUI has an export TAB that enables the user to export the residual, total model, and individual models as an object with the type of the input object and as ASCII.
  • The SpectrumFitter (commandline version) accepts Container with PointSpectrum and SpectralSegment index.
  • The SpectrumFitter (commandline version) has methods to export the data as the input type and as ASCII.
  • The SpectrumFitter (commandline version) has method that returns a Jython script

Data interpolation

Random Numbers

  • New random numbers generators from different distribution: Uniform, Gaussian, Poisson, Gamma, Cauchy (Lorentz), Exponential and Jeffreys.

Statistics functions

  • RMS has been renamed to QRMS
  • RMS implements a new functionality (see URM)
  • Improved StdDev and Variance algorithms.
  • Improved CorrelateMatrix algorithm.

New functions
  • GeoMean which calculates the geometric mean of a array of numeric data types with 1 to 5 dimensions.
  • Mode which returns the mode(s), or the most common element(s), of an array of numeric data with 1 to 5 dimensions.
  • Covariance which yields the covariance between two random variables/vectors x and y with finite second moments. If one vector is longer than the other, only the values up to the length of the shorter vector will be taken into account.
  • CovarianceMatrix which returns the covariance matrix of the input M x N matrix. The result is a N x N matrix with each i, j value equal to the covariance of the ith and jth columns of the original matrix.

Trend analysis

Mapping

Other functions

  • SigClip
    • Median mode uses Median Absolute Deviation instead of Standard deviation.
    • Iterative use is allowed.

Source extraction

  • No significant changes to functionality.

Images

Display

  • Images can be opened as RgbImage directly from the Navigator in HIPE.
  • Regular image files (jpg, gif, png, ...) are shown as preview in the outline when being clicked on in the navigator view of hipe.
  • 2 images can be compared by setting the opacity of the image. This can be done using the setOpacity(float) method or using a slider in the Image Display.

Instead of dragging a selection of spectra to the dataset parameter, the task is applied on either the displayed or the selected spectra within the plot.
  • Load selectable datasets from a product When opening the spectrum explorer on a Product, a selection table is displayed showing all datasets that are stored in this Product along with certain characteristics. Just as within the original spectrum selection panel, these datasets can be sorted by clicking on the headercolumns. To load a set of datasets instead of just one or all, select each row and right click to load the selected datasets.
  • Realtime statistics information Selecting the Statistics task within the Toolbox displays realtime statistics while dragging ranges in the plot.
  • Added relativistic frequency to velocity transform When changing the unit of the wave axis to velocity the transform is now relativistic

Analysis

    • For old observations in the HSA without this value, the method will return a null value indicating that this field was never set before

History

A new history dataset viewer is available: When you click on the History dataset in your product then two tables appear above another:

  • An overview table which shows all the tasks used to generate the product. For each task, the name, execution time, build number and used calibration files are shown.
  • When you click on a row in this overview table then a second table is shown with details for the selected task. This table contains the details of this task: For each parameter its simple value and some product information is shown (when available).

Product Access Layer

Cache

Several bugfixes to improve the effectiveness of caching and the robustness has been introduced. One of these is a check to verify that the default LocalStore directory is not modified at any time during the cache's existence, which is a common source of corruption of the cache.

HsaPool

Virtual Observatory

Installer

There was a major restructuring of the pre-installation steps
  • The Basic/Advance selection page has been removed.
  • The memory, proxy and versant settings were restructured. There are no separate panels asking if the user wants to set a proxy or a versant. There is a dedicated page for the proxy setting and one for the versant settings. In the top of the panel there is the question with a check box. Then there are the text fields not editable by default which will become editable upon user action on the above check box.
  • Instead of the old instrument selection page, the user will now be offered the following list with check boxes for selection:
    Option Description
    PACS (preselected by default) PACS pipelines and analysis tools for astronomers.
    PACS expert Extra instrument-related applications for Calibration Scientists.
    SPIRE (preselected by default) SPIRE pipelines and analysis tools for astronomers.
    SPIRE expert Extra instrument-related applications for Calibration Scientists.
    HIFI (preselected by default) HIFI pipelines and analysis tools for astronomers.
    HIFI expert Extra instrument-related applications for Calibration Scientists.

  • The instrument selection window should allow to click in any combination of items to install those components.
  • It should also allow the deselection of all instruments to get HIPE framework only for FITS i/o and numerics analysis.
  • If possible, the installer should inform the user of the amount of data to download for the selected combination of modules.
  • The Proxy selection page should contain the Yes/No button and the entry fields, which are kept in grey until "Yes" is selected. The default is kept to "No".
  • The Versant selection page should contain the Yes/No button and the entry fields, which are kept in grey until "Yes" is selected. The default is kept to "No".
  • The rest of the pages should stay as they are.

Documentation

To improve the quality of the examples, we have introduced automatic testing of (many of) the source code examples occurring in manuals such as the Data Analysis Guide and the HIPE Owner's Guide. We have also introduced automatic testing of the examples occurring in the User's Reference Manual.

HIFI

HIFI Software Configuration and Properties

  • Generally most HIFI properties have moved from the hcss.dp.hifi build to the hcss.icc.hifi (expert) area and it is recommended that all internal ICC users always install the expert build in order to be able to run the pipeline from level -1.0.

  • Those using the expert build and wishing to run the pipeline from level zero will need to set the property var.hcss.instrument = hifi ' this so the system knows to use the HIFI binstruct settings for reading the packets. Note those using the legacy hifi-new.props file will already have this property set.

  • The hcss.dp.hifi (non-expert) build has pre-configured pools to access the HSA and the local pool via the Product Browser and PAL Storage Manager

  • Unnecessary and deprecated properties files have been removed from the system

HIFI Calibration

  • The minimum and maximum chopper threshold values have been changed.
    • HkThresholdsContext_H fpuChopperMin -> -0.04
    • HkThresholdsContext_V fpuChopperMin -> -0.04
    • HkThresholdsContext_H fpuChopperMax -> 0.06
    • HkThresholdsContext_H fpuChopperMax -> 0.06
Previous values used were those appropriate for the Hot and Cold black bodies, which are not representative of the full, planned range of the chopper. As a result, the quality control flag "FPU Check: Chopper measured values differ from the commanded" had been frequently raised more than necessary.

  • The upper limit of the mixer current quality control check for HEBs (bands 6 and 7) have been decreased from 0.08 mA to 0.055 mA, where tests have shown the mixers start to be under-pumped.

  • Update to calibration tree for results of Mars beam measurements
The following items have been added to the HIFI Calibration tree for the aperture efficiencies (H and V), main beam efficiencies (H and V), and the half power beam widths (H and V) :
    • apertureEfficiency-H
    • apertureEfficiency-V
    • beamEfficiency-H
    • beamEfficiency-V
    • beamWidths-H
    • beamWidths-V

The approach so far is to strictly use observed numbers (see tables below with initial results), without involving fitting results or empirical formulas. In particular this means:

    • for beam widths the fitted widths of circular Gaussians, corrected for the convolution with the Mars disk. See Raphael Moreno's report for details. Open question: is the fit of a circular Gaussian correct? Need to check by how much Mars moved during an integration.
    • for main beam efficiencies the values derived using the observed beam widths for the beam coupling. It is not yet decided if an average value or a linear interpolation between (and beyond) frequencies produces the best results
    • for aperture efficiencies the values are derived, again, using observed beam widths for the coupling of the beam to the source.

In addition, the already available entries for the forward efficiencies (H and V) are updated from 1.0 to 0.96 (in all bands, all frequencies) to be compatible with above results. This requires the change of constant 1.0 to 0.96 .

Note these are still initial results, measurements from ODs 390, 391, 406 and 407 still need to be added. One can use the developer part of calibration tree, where newer values will be tested first, by setting the following property: Configuration.setProperty("hcss.ia.obs.cal.release", "developer")

Level 0 Pipeline

  • H and V spectrometer astrometry
SpectrumDatasets contain columns, in decimal degrees, for the commanded pointing (a position between the H and V beams known as the synthesized aperture), labelled longitude_cmd and latitude_cmd, while the actual coordinates for the spectrometer beam are found in the longitude and latitude columns.

HRS Pipeline

WBS Pipeline

  • Fixes for frequency calibration in the case that line centres fall precisely in the middle of two pixels

Level 1 Pipeline

Level 2 Pipeline

hifiPipelineTask

  • The path/filename for a user defined/edited pipeline algorithm can now be passed to the hifiPipeline task via the command line, previously this was only possible in the GUI.

obs =hifiPipeline (obs=obs, level2AlgoPath="/home/Me/myLevel2Algo.py")

The older method of defining a function with the def keyword in Jython and passing that function to the hifiPipeline task still exists

obs =hifiPipeline (obs=obs, level2Algo=level2PipelineAlgo)

  • hifiPipeline will make an ObservationContext even if creation of trend products fails
  • hifiPipeline GUI layout improved to make more efficient use of space

Products

DoDeconvolution

  • More understandable error message when deconvolution fails (usual due to poor data input)
  • Plotting of DSB solution as deconvolutions runs now possible when diag_mode_on selected

DoGridding

FitHifiFringe

  • It is now possible to remove the smoothed baseline calculated by FitHifiFringe from the spectrum, in addition to the fitted sine waves. This option (sub_base) should be used with care as real spectral features can be removed this way. For interactive fitting of polynomial baselines, the new task FitBaseline is recommended.
  • Tooltips implemented
  • Improved error messaging

HiClass export tool

  • HiClass will now appear an an applicable task for HTP as well as ObservationContexts

Flags

SpectrumExplorer (HIFI specifics)

HIFI DP scripts (User tool scripts)

  • Introduction of a new task, FitBaseline, to interactively fit and subtract or divide out baselines in HIFI spectra.

Documentation

  • New chapters in the HIFI User's Manual: "What was done to my data?" and "HIFI Baseline Removal"
  • Updates to the HIFI Users Manual: "HIFI cookbook", "Data Primer", "Running the HIFI Pipeline", "HIFI Standing Wave Removal Tool", and "Exporting HIFI data to CLASS"
  • Updates to HIFI Pipeline Specification document: improved pipeline flow diagrams, improved information about Euler resampling used in DoFreq grid task of pipeline
  • Creation of FitHifiFringe URM entry

Other

PACS

Pipeline

  • PACS "New Style Sliced" pipeline implementation is now activated
    • PacsSpr:2647 : phot and spec ipipe script names are changed to be more logic and intuitive
    • Pipeline Script access
      • HIPE -> Menu -> pipeline -> PACS
  • Calibration framework Calibration products are no longer delivered with the build in a local store.
    Calibration products are now delivered as a directory of FITS files.
    This directory with calibration products can be found in the data/pcal sub-directory of your installation directory.
    HIPE> fm = getCalTree(verbose=1)
    CalTree read from: /Software/Herschel/hcss.dp.pacs-5.0.500/data/pcal
    The calibration framework is adapted and will read these FITS files by default.
    The getCalTree() command and all access to calibration data has not changed, under the hood, the local store has been replaced by the directory of FITS files. Other small changes:
    • getCalTree(), getCalProduct() now understand the 'verbose=True' keyword and will print information on the location of the calibration products.
    • getCalProduct() the third argument, 'version', is no longer mandatory, if not given, the last version of the calibration product will be returned.
  • a new Pacs Documentation page has been opened on the public wiki.

Photometry

  • MadMap
    • Extended Madmap (using scan and cross scan) for interactive usage
      • HIPE -> Menu -> pipeline -> PACS -> L2_scanMap.py
        Based on HCSS-9361, a prototype for the extended Madmap pipeline is now available in HIPE for interactive usage. The extended Madmap pipeline is designed to combine scans and cross-scans in order to produce optional map. Unlike DP pipelines (which normally starts with one ObservationContext), this pipeline takes an obsList (an ArrayList) which is a list of ObservationContext. The pipeline will run even there is only one obs in the obsList. Below is an example creating an obsList:
        HIPE> obsList=ArrayList()
        HIPE> obsList.add(obs1)
        HIPE> obsList.add(obs2)

  • New script for scan Map pipeline

    • PacsSpr:2789: The MapIndexViewer has a Sigclip gui to display the effect of different Sigclip parameters on the second level deglitching. Now it is not necessary any more to guess Sigclip parameters, run the deglitching and check the quality afterwards. The new option allows to find the best parameter quickly BEFORE deglitching has been applied.
      The MapIndexViewer now also displays the signal vectors in the "timeordered" mode.
    • PacsSpr:2921: the MapIndexViewer shows mean/median +/- error permanently in the signal plot
    • PacsSpr:2807: the Full MapIndex needs less memory than before
    • PacsSpr:2859: Wcs4mapTask got a crota option to manually set the requested rotation angle of a map.

    • PacsSpr:2751 : photProject error map has been checked for NaN
    • PacsSpr:2543 : exposure map has been removed in favour of the coverage map
  • Noise treatmement
    • PacsSpr:2752: A new modul herschel.pacs.spg.phot.PhotAddNoisePerPixelTask provides 4 ways to calculate the initial photometer noise. *Noise propagation is also implemented in the HighpassFilter, Mean- and MedianFilters.
  • Pointing
  • Others
    • PacsSpr:2761 PACS EDP: phot pipeline adaptation to cope with variable scan velocity
    • A new module photMaskFrames offer masking :
    • framesOut = photMaskFrames(framesIn [,beforeFirstScanLeg] [,noScanData] [,afterCalblock=0] )
      • beforeFirstScanLeg : Mask data befor the first scan leg
      • noScanData : mask data where the ScanBBID is not set (includes turn arounds)

  • Extra options to specDiffChop (note these are EXPERT options for the analysis of special observations!)
    • PacsScr:2717: extra option 'extend' added which allows for other pairwise differencing schemes. These schemes will subtract more datapoints from each other than the standard scheme.
    • PacsScr:2427: extra option 'chopNodScheme' which provides different scheme for determining which label is on-source and which is off-source for a given nodding position. Needed for some special test AORs.
  • Different bands in a range scan are now stored in their own blocks in the block table. This means that it is now possible to slice SEDs per band (PacsScr:2963).
  • Several fixes to specWaveRebin, etc. to reduce the amount of NaNs considerably in the rebinned data.
  • SpecProject sets the flux to Jy.

    • This calibration product is used by the phase correction module to make the data symmetric prior to application of the Fourier transform.
  2. Spectrometer Instrument RSRF
    • This calibration product is used, along with the instrument temperatures from the housekeeping telemetry, to compute a model for the contribution to the measured spectra from the SPIRE instrument.
  3. Telescope RSRF
    • This calibration product is used, along with the Telescope temperatures from the housekeeping telemetry, to compute a model for the contribution to the measured spectra from the Herschel Telescope.
    • This calibration product is also used for extended source flux calibration.

Updated

  1. Point-source RSRF
    • This calibration product has been updated to use a higher signal-to-noise observation of Uranus.

Calibration Framework

  • Updated to match the new products and dependencies.
  • The spireCal task now has an option to read from a local pool.

Preprocessing

Engineering Conversion

Common Pipeline

  • Only minor changes in logs and documentation.

Photometer Pipeline

  • Pipeline scripts:
    • Added time correlation task and concurrent glitch deglitcher task in scan map pipelines
    • Comment out optical and electrical crosstalk corrections
    • Removed plotting blocks
  • Pipeline tasks:

Spectrometer Pipeline

The spectrometer pipelines have undergone major changes for version 5. It is HIGHLY recommended that users with data processed with older versions update to version 5 to reprocess their data.

Level-0 -> Level 0.5

No change

Level-0.5 -> Level 1 (IFGM)

  • Electrical crosstalk correction has been commented out of the SPG pipelines.

Level 1 (IFGM) -> Single-sided Fourier transform

  • Subtraction of the Instrument/Telescope contribution has been moved to the spectral domain.
  • Phase correction now uses a Jiggle dependent empirically-derived Non-linear phase cal product.

Single-sided Fourier transform -> Level 1 (SPEC)

  • Correction for the contribution of the SPIRE instrument. A new processing step has been added to remove from the measured spectrum the contribution from the SPIRE instrument.
  • Correction for the contribution of the Herschel Telescope. A new processing step has been added to remove from the measured spectrum the contribution from the Herschel Telescope.
  • Optical crosstalk correction has been commented out of the SPG pipelines.

Level 1 (SPEC) -> Level 2

  1. SOF1 Sparse spatial sampling mode
    • A minor change in that the point source calibration product is now tailored to spectral resolution and apodization.
  2. Mapping Modes
    • Added NaiveProjectionTask, a new task for creating spectral simple cubes from preprocessed spectral data. This task creates spectral cubes by averaging the flux of samples within each pixel. Pixels without samples are given a value of NaN.

Interactive Analysis and Tools

  • Added the new DTMosaic class that allows the user to plot data recorded by many detectors during one observation on a single page to compare data more effectively (mosaic plot). This features is available from HIPE command line or within DetectorTimelineExplorer
  • DetectorTimelineExplorer and DetectorTimelineExplorerComponent :
    • Added a new features that allows the creation of mosaic plot of the detectors via right-click on the desired array
    • Added a new Color&Mask Preferences panel
    • Improved the color scale (using the Color&Mask Preferences it is now possible to select the Min/Max value for the color scale)
    • Improved the mask visualization (using the Color&Mask Preferences it's now possible to visualize any specific mask value directly on the array display)
  • Made available the Mosaic class which creates a mosaic of plots in the shape of the SLW, SSW or coaligned detectors of the SPIRE FTS. The Mosaic class is intended to provide a means for viewing (at a glance) the spectra or interferograms associated with each detector.
  • Changed SpecExplorer's detector display so that it automatically re-sizes to fit the enclosing frame. Also, SpecExplorer's detectors are now enclosed in a splitter pane. This enables you to maximize or hide the detector display with a single click.
  • A new SpireMultiObs task to process several observations through the pipeline at once.
