FITS_GILDAS

        FITS_GILDAS

    Converts a disk FITS image in a GILDAS image.  A disk FITS image  is  an
    2880   bytes   per   block   file  conforming  to  FITS standard for the
    information written in  the  blocks.   Such  disk  FITS  images  can  be
    produced  by  other  packages (e.g.  AIPS).  This task is intended for a
    single image.  For many  images,  or  tape  FITS,  use  the  interactive
    program GFITS.

    Images are assumed to have at most  4  axis.  FITS_GILDAS  also  handles
    UVFIT data.

    Conversion for FITS to GILDAS data format is not necessary: "on-the-fly"
    conversion  of  FITS files into GILDAS images is automatically attempted
    by all GILDAS programs and tasks. This conversion  creates  a  temporary
    GILDAS  image  (of  extension  .fits.gdf) which is normally deleted upon
    completion. However, this "on-the-fly" conversion will fail if the  FITS
    keywords are highly non-standard.
