HIFI Data Processing Information

Updates to the HIFI HIPE pipeline

The following lists the major changes in the HIFI pipelines associated with each public user release of HIPE.

• HIPE 3.0
  • Improved velocity calibration (systematic offset [~2km/s] due to incorrect reference position removed)
• HIPE 4.0 (see also the What's new)
  • Separate pointing information for H and V polarizations available through reprocessing (see note above).
• HIPE 5.0 (see also the What's new)
  • Separate pointing information for H and V polarizations now applied by default in pipeline
  • Aperture efficiencies, Beam efficiencies and beam widths included in calibration tree. The output of the pipeline is now TA*, rather than TA‘
  • Forward efficiency of 0.96 now included in the calibration tree (its value was 1 before). Since a division by Feff is applied at the end of the level2, the overall intensity scale will be changed accordingly.
• HIPE 6.0 (see also the What's new)
• HIPE 7.0 (see also the What's new)

HIFI data processing documentation is predominantly available from within the HIPE data processing software. More specialist issues, such as deconvolution and standing wave removal (fringe fitter) are also discussed here.

• Link to all HIPE-related documentation, both PDF and HTML on the Herschel web site
• HIFI User's Manual for HIPE v7 (PDF) This is the main data processing documentation for handling HIFI data within the Herschel data processing system (HIPE).
• HIPE "read me first" document (PDF) Users new to data processing should read this document first when using HIPE.
• HIFI pipeline definition document v0.9 (28 July 2010, PDF)
• HIFI User's Reference Manual v3.0 (14 Dec 2010, PDF)
• HIFI Expert's Reference Manual v2.0 (14 Dec 2010, PDF)
• HIFI HIPE 5 DP updates
• HIFI HIPE 6 DP updates
