NEW NEW NEW Latest Updates (9-August-2016)

  • HIPE 14.2 has been released
  • PACS instrument data with HIPE 14.2 version bulk reprocessing has started (Note last bulk of PACS data was performed with 14.0.1)
  • Check calibration updates and improvements
  • Warning for pointing anomaly in HIPE/SPG 13/14: several PACS and SPIRE photometry observations reported are affected by a known problem related to the reset of the Spacecraft Velocity Vector (SVV) during the upload of the star-tracker's defective pixel table. For the affected observations, the pointing of the telescope can be off along the scan direction, and shifted up to 20 arcsec up to 14.0.1

  • HIPE 14.2.1 has been released.
  • Spectrometer Level 3 products have been reprocessed and are now properly concatenated including all corresponding obsids.
  • 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: 119 to 117
  HIPE (Herschel Interactive Processing Environment) is the tool used to inspect, reduce, and analyse Herschel data.

  • The recommended User Release HCSS (Herschel common science system) version that you should use for reducing PACS data is HIPE v14.2

  • 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):

  • The what's new in HIPE 14 page lists the changes in HIPE version 14.2 with respect to the 14.0, and provides a detailed list of updated functionalities, product changes, and calibration aspects.
  • The Data products known issues page details issues about the pipelines or the data products that are known about and offers advice for dealing with them. Consult this if you encounter problems with your data to see if it has already been addressed.

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:
