hifv_fluxboot

hifv_fluxboot(vis=None, caltable=None, fitorder=None, refantignore=None, refant=None) ResultsList[Results][source]

Determine flux density bootstrapping for gain calibrators relative to flux calibrator.

Parameters:
  • vis (str or list) -- The list of input MeasurementSets. Defaults to the list of MeasurementSets specified in the hifv_importdata task.

  • caltable (str) -- fluxgaincal table from user input. If None, task uses default name. If a caltable is specified, then the fluxgains stage from the scripted pipeline is skipped and we proceed directly to the flux density bootstrapping.

  • fitorder (int) -- Polynomial order of the spectral fitting for valid flux densities with multiple spws. The default value of -1 means that the heuristics determine the fit order based on fractional bandwidth and receiver bands present in the observation. An override value of 1,2,3 or 4 may be specified by the user. Spectral index (1) and, if applicable, curvature (2) are reported in the weblog. If no determination can be made by the heuristics, a fitorder of 1 will be used. Default is -1 (heuristics will determine).

  • refantignore (str) --

    String list of antennas to ignore

    Example: refantignore='ea02, ea03'

  • refant (str) --

    A csv string of reference antenna(s). When used, disables refantignore.

    Example: refant = 'ea01, ea02'

Returns:

The results object for the pipeline task is returned.
