With Python binding (which is normally provided), a default catalog
can be created (in the local directory) by executing once
@ gag_data:imager-linedb.sic
This may take a while, and even get stuck occasionally because it
performs network access to remote databases. You can later copy
this catalog to your $HOME. See HELP LINEDB\ to add or remove
species from such catalogs.
Without Python binding, IMAGER provides a default Astro catalog
in gag_data:molecules.dat.
