hifa_imageprecheck —- Calculates the best robust value and Briggs weighting parameter to achieve sensitivity and angular resolution goals.

In this task, the representative source and the spw containing the representative frequency selected by the PI in the OT are used to calculate the synthesized beam and to make sensitivity estimates for the aggregate bandwidth and representative bandwidth for several values of the robust parameter. This information is reported in a table in the weblog. If no representative target/frequency information is available, it defaults to the first target and center of first spw in the data (i.e. pre-Cycle 5 data does not have this information available). The best Briggs weighting parameter to achieve the PI’s desired angular resolution is chosen automatically. See the User’s guide for further details.

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

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

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

MeasurementSets specified in the h_init or hif_importdata task. ‘’: use all MeasurementSets in the context

Examples: ‘ngc5921.ms’, [‘ngc5921a.ms’, ngc5921b.ms’, ‘ngc5921c.ms’]

calcsb Force (re-)calculation of sensitivities and beams parallel Use MPI cluster where possible 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 just display the command (True) acceptresults Add the results of the task to the pipeline context (True) or

reject them (False).
