hpc_hif_refant —- Select the best reference antennas

The hpc_hif_refant task selects a list of reference antennas and stores them in the pipeline context in priority order.

The priority order is determined by a weighted combination of scores derived by the antenna selection heuristics. In manual mode the reference antennas can be set by hand.

Output:

results – If pipeline mode is ‘getinputs’ then None is returned. Otherwise the results object for the pipeline task is returned.

Issues

——— parameter descriptions ———————————————

vis The list of input MeasurementSets. Defaults to the list of

MeasurementSets in the pipeline context. Not available when pipelinemode=’automatic’. example: [‘M31.ms’]

field The comma delimited list of field names or field ids for which flagging

scores are computed if hm_refant=’automatic’ and flagging = True. Not available when pipelinemode=’automatic’. example: ‘’ (Default to fields with the specified intents), ‘3C279’, ‘3C279,M82’

intent A string containing a comma delimited list of intents against

which the selected fields are matched. Defaults to all supported intents. Not available when pipelinemode=’automatic’. example: ‘BANDPASS’, ‘AMPLI,BANDPASS,PHASE’

spw A string containing the comma delimited list of spectral window ids for

which flagging scores are computed if hm_refant=’automatic’ and flagging = True. Not available when pipelinemode=’automatic’. example: ‘’ (all spws observed with the specified intents), ‘11,13,15,17’

hm_refant The heuristics method or mode for selection the reference

antenna. The options are ‘manual’ and ‘automatic. In manual mode a user supplied referenence antenna refant is supplied. In ‘automatic’ mode the antennas are selected automatically.

refant The user supplied reference antenna for hm_refant=’manual. If

no antenna list is supplied an empty list is returned. example: ‘DV05’

refantignore string list to be ignored as reference antennas.

example: refantignore=’ea02,ea03’

geometry Score antenna by proximity to the center of the array. This

option is quick as only the ANTENNA table must be read. Parameter is available when hm_refant=’automatic’.

flagging Score antennas by percentage of unflagged data. This option

requires computing flagging statistics. Parameter is available when hm_refant=’automatic’.

pipelinemode The pipeline operating mode. In ‘automatic’ mode the pipeline

determines the values of all context defined pipeline inputs automatically. In interactive mode the user can set the pipeline context defined parameters manually. In ‘getinputs’ mode the user can check the settings of all pipeline parameters without running the task.

dryrun Run the task (False) or display the command (True).

Available when pipelinemode=’interactive’.

acceptresults Add the results of the task to the pipeline context (True) or

reject them (False). Available when pipelinemode=’interactive’.

parallel Execute using CASA HPC functionality, if available.
