transform

Split, average and/or calibrate the data.

enable

bool

Execute the transform worker.

label_in

str, optional, default = ‘ ‘

Label of the input dataset.

label_out

str, optional, default = corr

Label of the output dataset.

rewind_flags

Rewind flags to specified version.

enable

bool, optional, default = False

Enable the ‘rewind_flags’ segment.

version

str, optional, default = ‘ ‘

Flag version to restore. Note that all flag versions saved after this version will be deleted.

split_field

Make new MS of targets or calibrators.

enable

bool, optional, default = True

Enable the ‘split_field’ segment.

field

str, optional, default = target

Fields to be split off from the input MS. Options are (separately) ‘target’, ‘calibrators’, ‘bpcal’, ‘gcal’ and ‘fcal’. Also valid is any combination of ‘bpcal’, ‘gcal’ and ‘fcal’ in a comma-separated string (e.g. ‘bpcal, fcal’).

time_avg

str, optional, default = ‘ ‘

Time averaging to apply to the data, in units of seconds. If this parameter is instead set to ‘’ or ‘0s’ then no time averaging is applied.

chan_avg

int, optional, default = 1

Frequency averaging to apply to the data, given as the number of channels per frequency bin. If this parameter is set to ‘’, ‘0’, or ‘1’, then no frequency averaging is applied.

col

str, optional, default = corrected

Column to be split, where the default is ‘corrected’.

correlation

str, optional, default = ‘ ‘

Select the correlations, e.g. ‘XX’, ‘YY’. Setting this to ‘’ means that all correlations are selected.

create_specweights

bool, optional, default = True

Create a WEIGHT_SPECTRUM column in the output MS.

spw

str, optional, default = ‘ ‘

Select spectral windows and channels, following the same syntax as for the ‘mstransform’ task in CASA. Setting this to ‘’ means that all spectral windows and channels are selected.

otfcal

Apply on-the-fly (OTF) calibration.

enable

bool, optional, default = False

Enable the ‘otfcal’ segment.

callib

str, optional, default = ‘ ‘

Name of the callib file to be used, if user has their own.

label_cal

str, optional, default = 1gc1

Label of the calibration tables to be used.

changecentre

Change the phase centre.

enable

bool, optional, default = False

Enable the ‘changecentre’ segment.

ra

str, optional, default = 0h0m0.0s

J2000 RA of the new phase centre, in the format XXhXXmXX.XXs .

dec

str, optional, default = 0d0m0.0s

J2000 Dec of the new phase centre, in the format XXdXXmXX.XXs .

obsinfo

Get observation information.

enable

bool, optional, default = True

Enable the ‘obsinfo’ segment.

listobs

bool, optional, default = True

Run the CASA ‘listobs’ task to get observation information.

summary_json

bool, optional, default = True

Run the MSUtils summary function to get observation information written as a JSON file.

report

bool, optional, default = False

(Re)generate a full HTML report at the end of this segment.
