NAME

Astro::Catalog::Query::USNOA2 - A query request to the USNO-A2.0 Catalog

CONTENTS

SYNOPSIS



  $usno = new Astro::Catalog::Query::USNOA2( Coords    => new Astro::Coords(),
                                             Radius    => $radius,
                                             Bright    => $magbright,
                                             Faint     => $magfaint,
                                             Sort      => $sort_type,
                                             Number    => $number_out );

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



DESCRIPTION

The module is an object orientated interface to the online USNO-A2.0 catalogue at the ESO/ST-ECF archive site.

Stores information about an prospective USNO-A2.0 query and allows the query to be made, returning an Astro::Catalog::USNOA2::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.
