HIFI Calibration

Added:
>
>
  • Updates to table of unusable data frames
  • Quality flags are now raised for monitoring SEUs (Sudden Event Upsets)
 

HIFI Pipeline

hifiPipeline task

Changed:
<
<
  • Added a quality flag that is raised when doDeconvolution cannot complete in the Level 2.5 pipeline
>
>
  • The SPG version is now updated in the meta data when you run the pipeline
  • The pipeline will only try to run for spectrometers for which there is data at level 0 (previously the pipeline always tried to run for all spectrometers)
  • The option to customise the pipeline from the GUI is disabled by default when starting processing from Level 2
  • Mapping browse products changed so that the average spectrum and integrated cubes are shown for each subband separately
 

Level 0 Pipeline

Added:
>
>
  • The DoBadLo step (a step to flag out datasets known to be bad or unnecessary repeats) is reprocessed when a new calibration is passed to the pipeline.

 

WBS Pipeline

Changed:
<
<

HRS Pipeline

>
>
  • A new quality flag is introduced to warn of a single COMB failure
  • Improved checks and threshold values for the ZERO spectra.

<-- ---++++ HRS Pipeline -->
 

Level 1 Pipeline

  • Addition of a task to allow comparision of emission in DBS chop positions, !mkDbsReference task. Differences the chop positions in all DBS observations and after applying the band-pass correction stores them in a product in calibration->pipeline-out called ReferenceSpectra. You may configure the task to average the differenced spectra together (a resampling is automatically done) and to resample the spectra yourself.
Added:
>
>
  • Additional parameters available to DoFilterLoads
 

Level 2 Pipeline

Added:
>
>
  • DoAvgTask now propagates ra_center and dec_center to metadata
  • A new task, MkFLagSummaryTable, creates a table containing all the flags raised by the pipeline for quick inspection
 

Level 2.5 Pipeline

Added:
>
>
  • Rotated cubes are now produced by default for maps carried out with a non-zero position angle, a non-rotated cube is also produced.
  • Flagged data are omitted from spectral cubes
  • Added a quality flag that is raised when doDeconvolution cannot complete in the Level 2.5 pipeline
 

HIFI Products

  • HifiUplinkProduct format changed to a table dataset (easier to read)

Spectrum tasks (HIFI specifics)

Added:

>
  • A new task, !doOffset, to calculate the offset positions from the requested position is introduced. You can use it to switch between offset and absolute coordinates.
  • DoFold task now doubles in the reported integration times in the metadata after folding.
 

HIFI Data Processing Tools

Standing Wave Removal

Line: 196 to 217
 
  • Added a 'BRIGHT_LINE' toggle. If enabled, doDeconvolution will ignore data set with this channel flag. Useful for preventing `ghosts' of bright lines caused by the iterative nature of the deconvolution algorithm. You need to manually mask these lines using, for example, flagTool.
  • Plotting output has been cleaned up and simplified.
  • doDeconvolution now gracefully exits whenever it fails to process an observation (occurs only for the most troublesome of data and is rare).

Spectral Cube creation

Added:
>
>
  • The GUI will by default pick up the rotation angle (flyAngle in the GUI) used when the map was observed. When the pipeline is run with the interactive level 2.5 pipeline selected or modified in any way then only this angle will be used, when the pipeline is run with all the default settings then non-rotated and rotated cubes will be produced. In the case that the flyAngle is zero only one set of cubes will be created.
 

flagTool

Added:
>
>
  • Major updates to make the tool faster, more intuitive and easier to use:
    • All data are displayed in a table to the left of the plot, enabling you to quickly select the datasets you want to flag without needing to cycle through all the data if not required.
    • All subbands can be displayed together (without gluing).
    • Flag type can be selected from the options above the plot instead of from a context menu

Documentation

Added:
>
>
  • Updates to the HIFI Data Reduction Guide:
    • Addition of a chapter describing how to convert positions in data to offsets
    • Improvements and updates to "How to add and remove flags" chapter, including documentation of new flagTool in the "Setting flags interactively for many spectra" section
    • Improvements and updates to "Running the HIFI pipeline" chapter
    • Update to mapping browse product description in "Tour of a HIFI observation context" chapter
    • Removal of references to the old CubeSpectrumAnalysisToolbox and replacement with references to the new Cube Toolbox
    • Various typos, improvements to style consistency and bug fixes.
