Observing with HIFI

  • Useful Documentation
Line: 280 to 280
 
  • Information about how to find what calibration version was used on your data, how to get the latest calibration, and reprocess observations with it is found in the Pipeline chapter of the HIFI Data reduction Guide.

  • Updates to the HIFI calibration data are generally concurrent with the release of each major version of the HCSS-HIFI software. However, it is possible to have updates to the calibration data in between major releases of the software as the software and data are independent of each other, in the table below the HIPE or the OD from which the calibration updates apply are given. The calibration versions available since HIPE 5 are listed in the table below:
Line: 302 to 302
 
14_0 04-07-13   11.0 Update of the list of corrupted data-frames for flagging at Level 0
15_0 18-03-14   12.0 Update of the list of corrupted data-frames for flagging at Level 0, ingestion of the Electrical Standing Wave correction reference table
18_0 02-07-14   12.1 Update of the list of corrupted data-frames for flagging at Level 0, Absolute Pointing Error (APE) added to allow a quality flag to be raised in future releases in case of large pointing offsets, updates to allow IF-dependent corrections to sideband ratio, update to spur tables to store entry of spurs found by the ICC or a Key Programme, addition of an instrument uncertainty table (currently only placeholder)

21_0 09-04-15   13.0 Update of the beam parameters (coupling efficiencies, HPBW, 2-D beam maps - see also the beam section above), addition of a new table of expected spectral spurs to be masked by the pipeline in Spectral Scans, addition of a database of Electrical Standing Wave correction solution for observations in bands 6 and 7, addition of a new Error table that will be propagated into an error budget in HIPE 14 (currently only placeholder), introduction of IF-dependent sideband gain ratio (currently only true for the lower end of band 2a), update of the list of corrupted data-frames for flagging at Level 0
