hif_transformimagedata(vis=None, outputvis=None, field=None, intent=None, spw=None, datacolumn=None, chanbin=None, timebin=None, replace=None, clear_pointing=None, modify_weights=None, wtmode=None) → ResultsList[Results][source]

Extract fields for the desired VLASS image to a new MS and reset weights if desired.

Parameters:

  • vis --

    List of visibility data files. These may be ASDMs, tar files of ASDMs, MSs, or tar files of MSs, If ASDM files are specified, they will be converted to MS format.

    Example: vis=['X227.ms', 'asdms.tar.gz']

  • outputvis -- The output MeasurementSet.

  • field -- Set of data selection field names or ids, '' for all.

  • intent -- Set of data selection intents, '' for all.

  • spw -- Set of data selection spectral window ids '' for all.

  • datacolumn --

    Select spectral windows to split. The standard CASA options are supported

    Example: 'data', 'model'

  • chanbin -- Bin width for channel averaging.

  • timebin -- Bin width for time averaging.

  • replace -- If a split was performed delete the parent MS and remove it from the context. example: True or False

  • clear_pointing -- Clear the pointing table.

  • modify_weights -- Re-initialize the weights.

  • wtmode -- optional weight initialization mode when modify_weights=True

Returns:

The results object for the pipeline task is returned.
