=head1 NAME

Astro::FITS::HdrTrans::UIST - UKIRT UIST translations

=head1 SYNOPSIS

  use Astro::FITS::HdrTrans::UIST;

  %gen = Astro::FITS::HdrTrans::UIST->translate_from_FITS( %hdr );

=head1 DESCRIPTION

This class provides a generic set of translations that are specific to
the UIST camera and spectrometer of the United Kingdom Infrared
Telescope.

=head1 METHODS

=over 4

=item B<this_instrument>

The name of the instrument required to match (case insensitively)
against the INSTRUME/INSTRUMENT keyword to allow this class to
translate the specified headers. Called by the default
C<can_translate> method.

  $inst = $class->this_instrument();

Returns "UIST".
