Parameter Explanations

infile

''

name of input SD dataset

antenna

int(0)

select an antenna name or ID, e.g. 'PM03' (only effective for MS input)

row

''

select data by row IDs, e.g. '3,5,7' (''=all)

field

''

select data by field IDs and names, e.g. '3C2*' (''=all)

spw

''

select data by IF IDs (spectral windows), e.g. '3,5,7' (''=all)

restfreq

''

the rest frequency, e.g. '1.41GHz' (default unit: Hz) (see examples in help)

frame

''

frequency reference frame (''=current)

doppler

''

doppler convention (''=current). Effective only when spw selection is in velocity unit.

timerange

''

select data by time range, e.g. '09:14:0~09:54:0' (''=all) (see examples in help)

scan

''

select data by scan numbers, e.g. '21~23' (''=all)

pol

''

select data by polarization IDs, e.g. '0,1' (''=all)

blmode

'subtract'

baselining mode ('subtract' or 'apply')

blparam

*UNKNOWN*

per spectrum fit parameters

bltable

''

name of baseline table

outfile

''

name of output file (See a WARNING in help)

overwrite

False

overwrite the output file if already exists

keeprows

False

keep all rows of input scantable in output table [True, False]
