Astro::Catalog::Query::GSC - A query request to the GSC Catalog


  $gsc = new Astro::Catalog::Query::GSC( RA        => $ra,
                                         Dec       => $dec,
                                         Radius    => $radius,
                                         Bright    => $magbright,
                                         Faint     => $magfaint,
                                         Sort      => $sort_type,
                                         Nout      => $number_out );

  my $catalog = $gsc->querydb();


The module is an object orientated interface to the online Guide Star catalogue at the ESO/ST-ECF archive site.

Stores information about an prospective GSC query and allows the query to be made, returning an Astro::Catalog::GSC::Catalog object.

The object will by default pick up the proxy information from the HTTP_PROXY and NO_PROXY environment variables, see the LWP::UserAgent documentation for details.

See Astro::Catalog::BaseQuery for the catalog-independent methods.
