0.1.22 exportfits
Requires:
Synopsis
Convert a CASA image to a FITS file
Description
CASA-produced images can be exported as FITS files for transporting to
other software packages or publication. No subimaging of the fits image can be
made with this task. The spectral reference frame can be changed prior to
export using the task imreframe.
