Define variables associated to both the content and the header of the
GILDAS images located in the files, if specified. This command acts as a
combination of DEFINE HEADER and DEFINE TABLE. It accepts the same key-
words (KeyN) as DEFINE TABLE. If the keyword is READ, the header vari-
ables are mapped ReadOnly, otherwise they are mapped ReadWrite.
See HELP DEFINE HEADER for a description of the individual header vari-
ables.
FITS cubes can also be loaded as a Gildas image variable, using the FITS
file name in place of the file name. There will be no disk-to-disk
translation: at load time, the FITS header will be translated on-the-fly
to the GDF header elements, and the data will also be converted on-the-
fly if needed.
This feature is only available for cube-like data in Primary HDU. To
load other HDUs, use disk-to-disk conversion with the command V\FITS
/HDU.
