sdsave – Save the sd spectra in various format – single dish task

Description

Task sdsave writes the single dish data to a disk file in specified format (ASAP, MS2, SDFITS, ASCII). It is possible to save the subset of the data by selecting field names, spw ids, time ranges, scan numbers, and polarization ids. The ASAP (scantable) format is recommended for further analysis using Sd tool or tasks except imaging. For further imaging using imager or sdimaging, save the data to the Measurement Set (MS2).

overwrite	`False`	overwrite the output file if already exists [True, False]

Parameter Explanations

infile

''

name of input SD dataset

splitant

False

split output file by antenna (only effective for MS input)

antenna

int(0)
