What's new in HIPE 13

Highlights

• Core

• • HIPE now opens ALMA files and identifies ALMA cubes as spectral cubes, displayed in the Spectrum Explorer.
  • A rescue mode has been added to HIPE for cases where intensive scripts or memory thrashing issues make the GUI unresponsive.

• A new level 2.5 product has been generated for point mode observations. It is a stitched version of the level 2 spectra for each available spectrometer, in the form of a Spectrum1d.
• All observations context will now contain a (Ta*) calibrated OFF position spectrum, in the same sky frequency scale as the ON position data.

• In bands 6 and 7, the Electrical Standing Wave correction is now part of the standard pipeline, based on a data-base of optimised solutions stored in the calibration tree for each observation
• For spectral scans, a significant fraction of the deconvolved level 2.5 products will benefit from flag tables optimised manually by the ICC, resulting in spur-free deconvolved spectra. This is not yet available for all spectral scan obsids though, but will be by HIPE 14. The list of optimised flags can be found in the calibration tree and further refined by the user using the flagTool if the User wishes so.
• HIFI has a particular approach to the new gyro-based pointing reconstruction. The peculiarity of the approach and recommendation to the archive user are summarised in this memo.

import sys

Then the output of this script would be:

> hipe test.py arg1 arg2 arg3

Transitions

• Backups for new files are automatically created, and reopened in a subsequent session upon crashes like a power cut. If the session terminates gracefully, the backup files are deleted.
• Editing metadata and dataset cells in the Product or Observation viewers keeps the result in memory, and the table is refreshed accordingly with the new value.
• Animations when maximizing or restoring parts of the viewer will be shown (see Transitions).

• The ArrayDataset viewer shows the unit when specified.
• Column objects from a TableDataset have now a custom viewer.

Status bar

• Show the MyHSA on-line/off-line checkbox in the status bar.
• Hide the MyHSA on-line/off-line checkbox in the status bar.

Miscellany

• The Login panel is shown back at the top left corner of the Data Access perspective, and it has been simplified.

Plotting

• PlotXY no longer has an explicit way of forcing a batch of plotting statements. This is now done automatically and the script developer must not do anything special to take advantage of it.

Astronomical utilities

• Special corrections in pointing products to handle S/C operational events have been included in the auxiliary processors. Namely, the corrections are:
  • STR switch-overs, i.e. changes from the usually prime star-tracker (STR1) to the backup unit (STR2)
  • Reset of the Spacecraft Velocity Vector (SVV) that is used by the STR to compute the aberration correction of the coordinates of guide stars.

Numeric routines

• Temporal files for mapping are now created in a subdirectory: each HIPE session running will use a different subdirectory.

Images

• Replaced setCutLevels() by calcCutLevels()

• The zoom in / out was by a factor of 4 instead of 2.
• The Wcs viewer only shows the important wcs keywords now.

• Mosaics close to the north or south pole missed a part of the sky.

• You can choose to add an input parameter to annularSkyAperturePhotometry for choosing the step size of curve-of-growth output.

Spectra

• multiFit task now accepts limits for the model parameters.

Data cubes

• Disable the selection tools when some other data cube than the flux is shown.
• Fixed bug in which the upper and right rows and columns were not included in the selection for the cropCube task.

• Moment algorithm in computeVelocityMap improved with 'line strength' weighting. Especially dispersion is more accurate.
• Show proper model cube when absorption line fitting is done in computeVelocityMap.

Tasks

• Conversion tool to adapt multi-output tasks to new style in off-line User scripts.

• Preference "Generate task calls that returns full set of outputs" removed: tasks GUIs now always generate a call with the expanded list of outputs assigned to.
• Task status messages appear in the status bar
• convertUnits : It can convert units from double parameters, array datasets and columns, plus units from table datasets or products, by allowing to select the target dataset or column.

Quality control

• It is possible to create Quality Control summaries for several instruments in one go.

HIFI Data Processing Tools

Standing Wave Removal

• Updates to default band-dependent period characteristics in task fitHifiFringe :

• • Band 2,5 no change
• swTable had wrong unit for amplitude (kHz instead of K). This is now fixed.
• New output variable swTable was created to enable machine-readable output of fitted frequencies and amplitudes.

• Level2 products: the quality of the High-pass Filtered Level2 products (HPPPMAP) is improved by adding the scanamorphosMaskLongTermGlitches() and the scanamorphosBaselinePreprocessing() tasks, which can detect jumps and correct for drifts on the detector timelines.
• Level2.5 products: Unimap Level2.5 contexts contain the same types of maps generated by MADmap (naïve, GLS and Post-GLS), but they are arranged differently within the context (see Product changes).
• Level3 products: High-pass Filtered maps (HPPHPFMAP) have been removed from Level3 products, leaving JScanam and Unimap maps. Level3 mosaics are created by using scanamorphosAlignImages(), a new task that links the flux by exploiting overlapping regions between images.

• Harmonisation of map pixel sizes: at any Level, maps have the following pixel sizes:
  • 3.2 arcsec for the red channel, Prime and Parallel Modes;
  • 1.6 arcsec for the blue channel, Prime Mode;

• One of these three cubes is also provided with an equidistant wavelength grid, created with the new task specRegridWavelength.
• Tables containing the data of the rebinned cubes are created produced with the new task pacsSpecCubeToTable (HPSTBRR and HPSTBRB). The spectral data of each spaxel of each raster position is included in a single table, and each wavelength range and camera is a separate table.
• Flags are now also propagated by specProject and specInterpolate.

Analysis tools

Spectroscopy

Interactive Analysis and Tools

Photometer

Spectrometer

• New GUI interface for the script that determines the noise level in a spectrum.
• Small corrections to the useful scripts.
