build_cont_dat

interferopy.casatools_vla_pipe.build_cont_dat(vis='', line_freqs=[], line_widths=[], fields=[], outfile='cont.dat', overwrite=False, append=False)[source]

Creates a cont.dat file for the VLA pipeline. Must be run in CASA (uses msmetadata). It currently reads SPW edges in the original observed frame (usually TOPO), but writes them down as LSRK. Should not matter much, edges should be flagged anyway. Example of cont.dat content from NRAO online documentation: https://science.nrao.edu/facilities/vla/data-processing/pipeline/#section-25

Parameters

  • vis – path to the measurement set

  • line_freqs – line frequencies (obs frame, LSRK) in GHz

  • line_widths – widths of lines (obs frame, LSRK) in GHz to cut from the continuum

  • fields – science target fields. If empty, TARGET intent fields are used.

  • outfile – path to the output cont.dat file

  • overwrite – if True and the outfile exists, it will be overriten

  • append – add at the end of existing cont.dat file, useful for optimising lines per field

Returns

None
