Example
Keyword arguments:
infile -- Name of input SD dataset
calmode -- Gain calibration mode. Currently, only ’doublecircle’ is supported.
options: ’doublecircle’
default: ’doublecircle’
>>> calmode expandable parameter
radius -- Radius of the central region for double circle calibration.
Default (’’) is a radius of the primary beam. If numeric value
is given, it is interpreted as a value in arcsec.
default: ’’
options: ’20arcsec’, 20.0
smooth -- Whether apply smoothing during gain calibration or not.
options: (bool) True, False
default: True
antenna -- select data by antenna name or ID
default: ’’ (use all antennas)
example: ’PM03’
field -- select data by field IDs and names
default: ’’ (use all fields)
example: field=’3C2*’ (all names starting with 3C2)
field=’0,4,5~7’ (field IDs 0,4,5,6,7)
field=’0,3C273’ (field ID 0 or field named 3C273)
this selection is in addition to the other selections to data
spw -- select data by spw IDs (spectral windows)
NOTE this task only supports spw ID selction and ignores channel
selection.
default: ’’ (use all spws and channels)
example: spw=’3,5,7’ (spw IDs 3,5,7; all channels)
spw=’<2’ (spw IDs less than 2, i.e., 0,1; all channels)
spw=’30~45GHz’ (spw IDs with the center frequencies in range 30-45GHz; all channels)
this selection is in addition to the other selections to data
NOTE spw input must be ’’ (’’= all) in calmode=’tsys’.
scan -- select data by scan numbers
default: ’’ (use all scans)
example: scan=’21~23’ (scan IDs 21,22,23)
this selection is in addition to the other selections to data
NOTE scan input must be ’’ (’’= all) in calmode=’tsys’.
intent -- select data by observational intent, also referred to as ’scan intent’
default: ’’ (use all scan intents)
example: intent=’*ON_SOURCE*’ (any valid scan-intent expression accepted by the MSSelection module can be specified)
this selection is in addition to the other selections to data
applytable -- List of sky/Tsys calibration tables you want to pre-apply.
default: ’’
outfile -- Name of output caltable.
default: ’’ (<infile>_<suffix> for calibration)
overwrite -- overwrite the output caltable if already exists
options: (bool) True,False
default: False
