Define or list the current catalog(s) for spectral line identification. With argument NONE, the active catalogs are discarded. With no argument or argument ?, the command will just list the names of the current catalog(s).
A catalog is a file in the "Astro" GILDAS format, as used in programs ASTRO or CLASS in the GILDAS suite, or in the LINEDB\ data format (which requires Python binding).
There can be only ONE Astro catalog connected at a time, and it is exclusive of any LINEDB data bases. On the opposite, there may be several LINDEB data bases specified by the CATALOG command.
At initialization, IMAGER search for $HOME/imager.linedb as default catalog, then gag_data:imager.linedb if not found. If the specified catalog does not exist, IMAGER falls back to the gag_data:molecules.dat Astro-format catalog.
Caution: although direct use of the LINEDB\USE command is also possible to define the LINEDB catalog(s), this is not recommended as it may result with possible conflicts with an Astro catalog.
