CATALOG Default

        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.
