Core system


Main window

The state of the main window (size, location, maximized state) is remembered among HIPE sessions, so it is not necessary to set it after every start-up.

Startup & shutdown

Check of local pool locks (probably left from a previous session that was abnormally terminated) is executed at startup. This check is configurable in preferences.

Editor area & Viewers

  • The tabs within the Editor area show the close button even if not selected, so they can be closed with 1 click instead of 2.
  • The list of viewers shown in the Open With menu for the selected variable is more specific.
  • The viewer of lists shows the data values instead of just their type.


Context sensitive help on the focused view added. It can be accessed through Help > Help on <name> view or with F2.



  • TablePlotter now supports the axis.Date functionality.


  • OverPlotter now supports the axis.Date functionality.

  • Multi-threading: increasing speed of tasks significantly on multi-core machines



  • Reworked the save methods on Display. You can now save to jpg, png, eps or pdf files. The methods to use are :
    • save(filename), saveAsEPS(filename), saveAsPNG(filename), saveAsJPG(filename) and saveAsPDF(filename) : These methods will save the full image, including annotations.
    • saveCurrentView(filename), saveCurrentViewAsEPS(filename), saveCurrentViewAsPNG(filename), saveCurrentViewAsJPG(filename) and saveCurrentViewAsPDF(filename) : These methods will save the current view of the image, including annotations and axes.
  • The coordinate axes on the image panner are always visible now
  • There is a preference for image display to turn of the echoing of commands to the command line. It is possible to turn all these commands off, or only the zoom commands.
  • Flagged out pixels and pixels with a value of NaN will be shown in the color of the background.
  • Image can be matched with the Wcs. This means that the images can be oriented so that north is shown at the top and east to the left.
  • There is a preference for image display to always show the image with the 'match wcs' orientation.
  • A lot of bugfixes.





  • The Smooth task is corrected for a bug in the ZEROS option.
    • As a consequence of this fix, which is more mathematically correct, it is found that smoothed spectra for SPIRE are quite changed. It is recommended instead to use the REPEAT option.

Data cubes



Herschel Science Archive

  • Improvements in download speed and memory requirements for data downloaded from HSA using a behind-the-scenes utility called MyHSA
    • Testing with 5 HIFI, 9 PACS and 10 SPIRE representative observations of all major observing modes simultaneously with getObservation/saveObservation and with getObs/MyHSA with the same network connection on two different machines show 20 times faster download speed and that 66% less hard disk space is needed to hold the same data:

Observation context

Product Access Layer

When storing pools on shared NFS-mounted disks, HIPE now uses a more robust mechanism to prevent corruption. The default locking mechanism for Local Pools was changed to a mechanism that works more reliably on remote disks.

Usability improvements for the Product Browser and for working with tags. One can now update existing tags (for example to fix a typo).

  • Inclusion in the pipeline GUI of a drop-down box to select calibration version

Level 0 Pipeline

  • flagging of rare corrupted data-frames according to a list of pre-defined data-frames indices. The difference will only be noticed after the bulk reprocessing has taken place

HIFI Spectrum Toolbox

Spectrum Explorer (HIFI specifics)

Spectrum tasks (HIFI specifics)

  • ConvertK2Jy now uses the same scheme as doGridding to select frequency when interpolating the efficiency values from the calibration tree: the task searches first for the LO Frequency in the metadata, if it is not found the task looks in the metadata for the value inserted in HSpot. If neither are found then the middle frequency of the observing band (e.g. band 1a) is used.
  • Bug fix in ConvertK2Jy: non-zero source size data on frequency scale can now be converted to Jy
  • introduction of a new "accumulate" task allowing to automatically combine data taken on different frequency grids, with or without frequency overlap.

Engineering Conversion

Common Pipeline

Photometer Pipeline

  • DestriperTask
    • Added the "useSink" task parameter. The default value is False. It if it is set to True, the ProductSink on disk is used for the Level 1 output. This allows larger observations to be processed with a limited amount of RAM, but makes the task slower.
    • Added the "nThreads" task parameter. The default value is 1. The parameter specifies the number of threads to use, increasing speed significantly on multi-core architectures.
    • Implemented Level2 deglitching. The new "l2DeglichAlgorithm" task parameter specifies the algorithm to be used and can be set to "sigmaKappa" (default) or "twoSigmas".
    • Added the "l2IterMax" task parameter. It limits the number of iterations of the Level2 deglitcher within a destriper iteration. The default value is 5.
    • Added the "startParameters" task parameter. This input parameter accepts a diagnostic product that was provided at the end of a prior destriper run. It contains a table dataset with the last fit parameters and a flag column that determines which scans were excluded. Manual changes to these flags will be honored by a second destriper run in an interactive analysis session. If provided, the contents of the table are used as start parameters for a new destriper run, enabling faster convergence, and improvements to the map by deselecting "bad" scans. The default value is null.
    • Added the "storeTod" task parameter. The default value is False. In this case no TOD files will be stored and the returned TOD parameter is null. Setting the parameter to True, returns a TOD product and leaves the associated files (pixel, signal and weight) stored in the temporary directory until the end of the HIPE session.

  • Cooler Burp
    • A new task called RecalcTempDriftTask to deal with the cooler burp problem was introduced in the build. During the cooler burp the drifts of bolometers is unusual and for this reason the temperature drift correction leaves residuals. The proposed solution is a empirical solution that assume that the problem is due a change in temperature drift coefficients A used in TempDriftCorrectionTask. These parameters are normally read from calibration table and are necessary to link bolometers' signal and voltage thermistors. The task recalculates the A parameters via linear fitting of uncorrected signal vs thermistor voltages and the new parameters are then used in TempDriftCorrectionTask.
    • The user photometer pipeline scripts for parallel and large map observations was modified introducing the possibility to check for cooler burp and to use this new task to correct it. To do this, a new boolean parameter was introduced at the start of the user scripts: coolerBurpDetection. The default value is false, the user that wants check for the cooler burp he must set this parameter value to true.

Spectrometer Pipeline

Interactive Analysis and Tools

  • SpireMaskEditor
    • Level0_5 SpireMaskEditor was added to the right click menu on an observation context. It is used for displaying and editing the mask data of a Level0_5 Context.
    • Level1 SpireMaskEditor was added to the right click menu on an observation context. It is used for displaying and editing the mask data of a Level1Context.
    • These two additions effectively replace the SpireMaskEditorComponent which was deprecated.
