Scripts to assist VLBI data reduction in CASA
The functionality of the append_tsys.py, gc.py and flag.py scripts is also available in Python modules. The following interfaces are available:
casvlbitools.fitsidi.append_tsys(andtabfile, idifiles)Append Tsys measurements from the file named by antabfile (which
should be in AIPS ANTAB format or VLBA VLOG format) to the FITS-IDI
file named by idifiles. If an observation is split into multiple
FITS-IDI files, idifile should be a list of file names.
casvlbitools.fitsidi.append_gc(andtabfile, idifile)Append gain curves and sensitivity information from the file named by
antabfile (which should be in AIPS ANTAB format) to the FITS-IDI
file named by idifile.
casavlbitools.casa.convert_gaincurve(antabfile, gc, min_elevation=0.0, max_elevation=90.0)Create a gaincurve table with name gc from gain curves from the file
named by antablfile (which should be in AIPS ANTAB format or VLBA
gains format). The gain curves are sampled between min_elevation
and max_elevation, which should be specified in degrees, and then
refitted.
casavlbitools.fitsidi.convert_flags(infile, idifiles, outfp=sys.stdout, outfile=None)Convert the flag file named by infile (which should be in AIPS UVFLG
format) into a format that can be used by CASA. The name of the
FITS-IDI files corresponding to the observsation should be passed in
idifiles. By default the converted output is written to stdout.
Output is written to a file named outpufile instead if that
parameter is provided.
