Do basic deterministic flagging.

The hifv_flagdata task performs basic flagging operations on a list of MeasurementSets including:

  • autocorrelation data flagging

  • shadowed antenna data flagging

  • scan based flagging

  • edge channel flagging

  • baseband edge flagging

  • applying online flags

  • applying a flagging template

  • quack, shadow, and basebands

  • Antenna not-on-source (ANOS)

Parameters:

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

  • autocorr -- Flag autocorrelation data

  • shadow -- Flag shadowed antennas

  • scan -- Flag specified scans

  • scannumber --

    A string containing a comma delimited list of scans to be flagged.

    Example: '3,5,6'

  • quack -- Quack scans

  • clip -- Clip mode

  • baseband -- Flag 20MHz of each edge of basebands

  • intents --

    A string containing a comma delimited list of intents against which the scans to be flagged are matched.

    Example: '*BANDPASS*'

  • edgespw -- Fraction of the baseline correlator TDM edge channels to be flagged.

  • fracspw -- Fraction of baseline correlator edge channels to be flagged.

  • online -- Apply the online flags.

  • fileonline -- File containing the online flags. These are computed by the h_init or hifv_importdata data tasks. If the online flags files are undefined a name of the form 'msname.flagonline.txt' is assumed.

  • template -- Apply a flagging template.

  • filetemplate -- The name of a text file that contains the flagging template for RFI, birdies, telluric lines, etc. If the template flags files is undefined a name of the form 'msname.flagtemplate.txt' is assumed.

  • hm_tbuff -- The time buffer computation heuristic

  • tbuff -- List of time buffers (sec) to pad timerange in flag commands.

  • flagbackup -- Backup pre-existing flags before applying new ones.

Returns:

The results object for the pipeline task is returned.

Examples

  1. Do basic flagging on a MeasurementSet:

>>> hifv_flagdata()

2. Do basic flagging on a MeasurementSet as well as flag pointing and atmosphere data:

>>> hifv_flagdata(scan=True intent='*BANDPASS*')
