Highlights

HIPE

HIFI

PACS

SPIRE

• FTS
  • Two new tasks and corresponding calibration products have been introduced for SPIRE FTS data. One task corrects for artefacts in low resolution point source calibrated spectra. The other corrects the level of all extended source calibrated data in or to get better agreement between the SPIRE Spectrometer and Photometer.

Core system

HIPE

Editors & Viewers

Default editor

The default editor for every type of data, which is the one used when double clicking on a variable, is preserved regardless the editors opened through the Open With menu.

The previous behaviour, which is to use the last opened editor as the default, can still be set, by means of a new preference in the Editors & Viewers category.

Recent open files

The size of the recently opened files list, which can be accessed through the File menu, is now configurable through preferences.

Metadata tables

A new option in the popup menu of metadata tables allows copying cell values in other way than with the usual key combinations (Ctrl+C or Cmd+C).

Array data viewer

The array data viewer shows tooltips over the spinners (above the data table) for informing about the array dimensions.

Quick Analysis

There is a new perspective in HIPE, which is accessible by clicking on the magnifying glass at the top right toolbar, for quickly inspecting scientific data from the Herschel Science Archive.

Observations can be searched by target name, observation id, operational day or Ra/Dec.

When clicking on an observation, its standalone browse products are opened in the editor area for quick analysis, by means of the image, spectra or cube viewers.

Opening the observation context instead is also possible, either with the popup menu or by configuring so as the default behaviour, in the Quick Analysis preferences category.

Command line

It is now possible to pass arguments to HIPE from the command line, which will be tried to be interpreted as files to be opened with the proper viewers. For example:

bash> hipe myImage.jpg cube.fits resultTable.csv

would open HIPE with three viewers: one for the image, a spectrum explorer for the cube, and a dataset viewer for the CSV table.

Note:

Passing a Jython script as the first argument will still behave as running HIPE in batch mode:

bash> hipe myScript.py arg1 arg2

would not open the HIPE window, but execute the script with the given arguments passed to it.

Console

There are interesting enhancements in the Console view with HIPE 14.0:

• Text edit options (cut/copy/paste) are available not only by the usual key combinations, but also with the popup menu.
• Autocompletion through the tab key has been tremendously improved in this release, making Jython coder's life much easier.
• The console built-in help, shown with !help, is now more practical and understandable.

Products and datasets

A new Auxiliary Observation Summary Product which can be retrieved using the tag LATEST_OBSERVATION_SUMMARY_PRODUCT. This product contains one dataset with a summary of information for each observation. Useful methods exist for querying the data as documented here: ObservationSummaryProduct

Observation context

A new Calibration Table Product exists under the Auxiliary Context in each Observation Context. This product contains calibration tables data for the given instrument including exactly how the hardware was configured, hard limits, soft limits etc. This provides valuable information for the long term completeness of an observation. Useful methods exist for querying the table data as documented here: SimpleCalTableProduct

Product Access Layer

Tasks

Improved history recording so that it can be added to the sub-products of a context.

Quality control

Reorganization of quality flags as private or public for HCSS, HIFI, PACS and SPIRE Quality Flags. This ensures that only the flags useful for the assessment of the science by the user (the public ones) make its way to the quality summary.All the information from the quality flags remain at the quality product, for internal assessment or history.

In the quality report, a new "Ïmpact" column in the "Quality flags" table, after "Concept" and "Value" columns has been added. This new column is an automatically filled column with a brief text describing the possible consequences for science data from the situations that caused that quality flag to be raised.

Improvement of readability of quality flags in the meta data of products in FITS files. Now one meta data item per quality flag making proper use of parameter values and descriptions.

eg.) qflag_PARXXXXX_p <value> ⁄ <description>

Systematic product generation

Data input-output

Virtual Observatory

Installer

The user installer has been reduced by 400-800MB by removing the pointing distortion maps previously included with the data a part of user installation.

Documentation

For HCSS 14, many figures were refreshed in both manuals (HIFI Data Reduction Guide and HIFI Pipeline Specification).

• Updates to the HIFI Data Reduction Guide:
  • Updates to the chapters Standing wave Removal and HIFI Baseline Removal : adding definition of the new parameter addMedianContinuum
  • Updates to the chapter Flags in HIFI data, section Quality Flags (this chapter is being revamped, please check regularly)
  • Updates to the chapter How to make a spectral cube: added a definition for parameters ignoreOffs, outputNames and extrapolate
  • Updates to the chapter Sideband Deconvolution: the output deconvolution product ssb is now called dataset (please note that scripts prior to this change will break)
  • Updates to the chapter Standing wave Removal, ESW correction in HEB bands section: update to the scripts in the demonstration subsection
  • Updates to the chapter How to add and remove flags, section Setting and Clearing Flags with command line tools: improved the definition of the parameter selection for Level 2.5 cubes
  • A new chapter called Understanding the uncertainty table information in your data has been added
• Updates to the HIFI Pipeline Specification manual
  • This manual has been restructured
  • Removal of the task mkSpur
  • Corrections to broken links pointing to the HIFI Data Reduction Guide
  • Correction due to a missing figure Level 0 Pipeline flow diagram
  • Added text to tasks which did not have text, or were poorly documented, including mkRms

PACS

Pipeline

Photometry

• Level2.5 products:
  • Unimap and Jscanam maps are generated for Solar System Objects, by combining scan and cross-scan observations.
  • A block detection and masking method is implemented to avoid strong signal gradients generated by the calibration blocks. The quality of Level2.5 is enhanced in particular for those observations acquired at the early stage of the mission (e.g. Science Demonstration Phase) where calibration blocks were acquired in the middle of the scans.
• ipipe script:
  • The JScanam ipipe script scanmap_JScanam_multiplePairs is designed to process multiple pairs of obsIDs and it is upgraded by introducing the scanamorphosAlignFrames Task. This Task aligns the Frames signal levels, belonging to every observation, to a common offset level, by exploiting the overlapping sky regions. This new capability is particulary useful to recover a common background level over observations that are partially or slightly overlapping.
  • the script scanmap_Unimap_memory_optimized is added within the Pipelines menu for allowing to run the Unimap release located on the user’s computer by using the minimum amount of memory. It is particularly useful for processing large observations or/and if several obsIDs should be processed all together in a single run.
  • the photextended_pipeline_L3 script is available within the Pipelines menu to generate mosaics of Unimpa and Jscanam Level2.5 maps
• Unimap : Unimap 6.2.0 is spawned by the Standard Product Generator (SPG) to create Level2.5 products. See the Photometer Data Reduction Guide and the offical Unimap webpages (http://infocom.uniroma1.it/unimap/) to know what's new about the 6.2.0 Unimap release.

Photometry

Spectroscopy

Analysis tools

Photometry

• The PhotometryConvolveResolution Kernel script was added within the PACS Useful Script section. This script convolves and regrids a map at a certain wavelength to the PSF of another map at longer wavelength, by using an appropriate kernel.

Spectroscopy

Product changes

Photometry

• The error layer within Unimap Level 2.5 products is renamed as stdDev, being the standard deviation computed at every sky pixel with respect to the samples that are falling on it. It can be properly assumed as the error map only if associated to the Naïve map.
