  • HIPE 14.2.1 has been released.

  • HIPE 14.2.1 has been released
  • SPG 14.2.2 products are being processed. This will include a subset of spectroscopy observations only:
    • The Level 2.5 for all unchopped range scans: previously the Level 2.5 were created incorrectly
    • The Level 3 for all chop-nod pointed range scans: this is being done to have a correct "ObservationSummary" included in the observation dataset, however the data themselves will be no different as the processing has not changed
    • A few isolated spectroscopy observations (1342247513, 1342246558,1342225987, 1342225145, 1342225789, 1342247790)
 
  • Due to a bug fixed in the 6.4.4 Unimap release within 14.2.1, the values of some Unimap parameters have been modified for a small set of observations.

Observing with PACS

The relevant documentation to read before working on PACS data for the first time are the following:

Line: 120 to 124
 
  • The recommended User Release HCSS (Herschel common science system) version that you should use for reducing PACS data is HIPE v14.2.1
  • In the CIB (continuous integration build) this version corresponds to Track 14, build 3597. The CIB is the continuously bug-fixed/upgraded/improved version of HIPE, which every few months (in the beginning of the mission) or yearly (in the post-operations phase) becomes a stable User Release.
  • Within HIPE you can access all the PACS data reduction documentation and the general HCSS and HIPE user documentation for Track 14 here. The documentation provided via HIPE opens in a web browser, but for those of you who prefer PDF, we include the PACS Data Reduction Guides as PDF files here (note that within the standalone pdf versions, external links will not work):

Cookbooks and interactive pipeline scripts

  • The various interactive pipeline scripts PACS photometry and spectroscopy provide in HIPE can be seen as cookbooks, since they take you through each pipeline, task by task, explaining briefly what each task does, commenting on the more crucial pipeline tasks, and showing you how to plot, image, visualise and inspect your data as you work through the pipeline. An example public observation is included with each so you can test it out before using it on your data. These data reduction scripts are available in HIPE under the menu: Pipeline --> PACS --> Photometer/Spectrometer.

  • The PACS Launch Pads are taken from the first chapters of the respective PDRGs and are a useful quick-start guide to loading your data into HIPE, looking at them, and then what to know and do before you begin reprocessing your data with one of the pipelines. From HIPE 14.2.1:

These can be gotten via HIPE itself or the links here (these are to the HIPE 15 versions, which are the same as the HIPE 14 versions)
