NAME ^

Astro::Catalog::Query::Vizier - A query request to the Vizier catalogs

SYNOPSIS ^

  $gsc = new Astro::Catalog::Query::2MASS( Catalog => '2MASS',
                                           RA        => $ra,
                                           Dec       => $dec,
                                           Radius    => $radius,
                                           Nout      => $number_out,
                                           Target    => $object,
                                         );

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

DESCRIPTION ^

The module is an object orientated interface to the online Vizier catalogs. Multiple catalogues can be specified using a comma-separated list.

Stores information about an prospective query and allows the query to be made, returning an Astro::Catalog::Query::Vizier 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::Query for the catalog-independent methods.

NOTES ^

See http://vizier.u-strasbg.fr/doc/asu.html for all the options supported by Vizier (although they will be the translated form rather than the abstracted arguments used by Astro::Catalog.
