hsd_flagdata —- Do basic flagging of a list of MeasurementSets

The hsd_flagdata data performs basic flagging operations on a list of MeasurementSets including:

o applying online flags o applying a flagging template o shadowed antenna data flagging o scan-based flagging by intent or scan number o edge channel flagging

Output:

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

defined in the pipeline context.

autocorr Flag autocorrelation data. shadow Flag shadowed antennas. scan Flag a list of specified scans. scannumber A string containing a comma delimited list of scans to be

flagged.

intents A string containing a comma delimited list of intents against

which the scans to be flagged are matched.

example: ‘BANDPASS’

edgespw Flag the edge spectral window channels. fracspw Fraction of the baseline correlator TDM edge channels to be flagged. fracspwfps Fraction of the ACS correlator TDM edge channels to be flagged. online Apply the online flags. fileonline File containing the online flags. These are computed by the

h_init or hif_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.

pointing Apply a flagging template for pointing flag. filepointing The name of a text file that contains the flagging template

for pointing flag. If the template flags files is undefined a name of the form ‘msname.flagpointing.txt’ is assumed.

incompleteraster Apply commands to flag incomplete raster sequence.

If this is False, relevant commands in filepointing are simply commented out.

hm_tbuff The heuristic for computing the default time interval padding parameter.

The options are ‘halfint’ and ‘manual’. In ‘halfint’ mode tbuff is set to half the maximum of the median integration time of the science and calibrator target observations.

tbuff The time in seconds used to pad flagging command time intervals if

hm_tbuff=’manual’.

qa0 QA0 flags qa2 QA2 flags 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.

flagbackup Back up any pre-existing flags before applying new ones. dryrun Run the commands (True) or generate the commands to be run but

do not execute (False).

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

reject them (False).
