sdcoadd – Coadd multiple scantables into one – single dish task

Description

Task sdcoadd performs co-add multiple single dish spectral data given by a list of spectral data file names in any of the following formats, ASAP, MS2,SDFITS, and ASCII. The units of line flux, the units of spectral axis, frame, and doppler are assumed to be those of the first one in the infiles.

The task tries to combine spws according to a tolerance value specified by the parameter freqtol. Default tolerance is ‘0Hz’, which means spws are combined only when spectral setup are the same. Note that, except for first data in the infiles, spw is ignored if there are no corresponding spectral data in the main table.

Parameters

Title
Parameter	Default	Description

outfile	`''`
outform	`'ASAP'`	output file format ['ASAP', 'MS2', 'ASCII', or 'SDFITS'] (See a WARNING in help)
overwrite	`False`	overwrite the output file if already exists [True, False] (See a WARNING in help)
