            Dec => $dec,
            Year => $year,
            Month => $month,

=head1 DESCRIPTION

This module provides an object-oriented interface to the Minor Planet
Center's Minor Planet Checker webform available at
http://scully.harvard.edu/~cgi/CheckMP. It stores information about
asteroids found in a search radius at a specific epoch in an
C<Astro::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 L<Astro::Catalog::BaseQuery> for the catalog-independent methods.
