What's new in HIPE 9

Line: 53 to 53
 
      • improved error maps (possibly as an option)
      • improved baseline correction using "destriper“
    • Interactive processing
Changed:
<
<
      • sourceExtractorTimeline task, for measuring source photometry using timeline data
      • improvements to bolometer finder tool
>
>
* sourceExtractorTimeline task, for measuring source photometry using timeline data * source timeline fitter task * improvements to bolometer finder tool
 
      • selection of turnaround data in map creation
  • Spectrometer
    • Pipeline Processing: smaller size for level 1 products
Line: 177 to 178
 

HIFI Calibration

Added:
>
>
  • New calibration database HIFI_CAL_9_0, containing the following updates
    • Side-band ratio correction over the whole of bands 5a and 5b
    • Update of a number of engineering threshold for more accurate quality flagging related to hardware housekeeping
    • introduction of a list of a priori known corrupted data-frames for dedicated flagging in level0 data
 

HIFI Pipeline

hifiPipeline task

Line: 184 to 190
 
  • Inclusion in the pipeline GUI of a drop-down box to select calibration version

Level 0 Pipeline

Added:
>
>
  • 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
 

WBS Pipeline

  • Introduction of quality flag to warn about a bad zero.
Line: 191 to 198
 

HRS Pipeline

Level 1 Pipeline

  • Addition of parameters in the doFilterLoads to allow configuration of the filtering.
Added:
>
>
  • Addition of a new quality products "flagsSummary" compiling the list of all rowflags set to the data at this level
 

Level 2 Pipeline

  • doAvg now honours user-defined flags, RowMask.IGNORE_DATA and HifiMask.IGNORE_DATA
Line: 209 to 217
 

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
Changed:
<
<
>
>
  • introduction of a new "accumulate" task allowing to automatically combine data taken on different frequency grids, with or without frequency overlap.
