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.
