Apply calibration tables to input MeasurementSets.

hifv_applycals applies the precomputed calibration tables stored in the pipeline context to the set of visibility files using predetermined field and spectral window maps and default values for the interpolation schemes.

Parameters:

  • vis -- The list of input MeasurementSets. Defaults to the list of MeasurementSets specified in the hifv_importdata task.

  • field --

    A string containing the list of field names or field ids to which the calibration will be applied. Defaults to all fields in the pipeline context.

    Example: '3C279', '3C279, M82'

  • intent --

    A string containing the list of intents against which the selected fields will be matched. Defaults to all supported intents in the pipeline context.

    Example: '*TARGET*'

  • spw --

    The list of spectral windows and channels to which the calibration will be applied. Defaults to all science windows in the pipeline.

    Example: '17', '11, 15'

  • antenna -- The selection of antennas to which the calibration will be applied. Defaults to all antennas. Not currently supported.

  • applymode --

    Calibration apply mode.

    • 'calflag': calibrate data and apply flags from solutions

    • 'calflagstrict': same as above except flag spws for which calibration is unavailable in one or more tables (instead of allowing them to pass uncalibrated and unflagged)

    • 'trial': report on flags from solutions, dataset entirely unchanged

    • 'flagonly': apply flags from solutions only, data not calibrated

    • 'flagonlystrict': same as above except flag spws for which calibration is unavailable in one or more tables

    • 'calonly': calibrate data only, flags from solutions NOT applied

  • flagbackup -- Backup the flags before the apply.

  • flagsum -- Compute before and after flagging summary statistics.

  • flagdetailedsum -- Compute detailed flagging statistics.

  • gainmap -- Mode to map gainfields to scans.

Returns:

The results object for the pipeline task is returned.
