Astro::Catalog::IO::UKIRTBS - Old format used by UKIRT Bright Star catalogues

SYNOPSIS

Top

  $cat = Astro::Catalog::IO::UKIRTBS->_read_catalog( \@lines );

DESCRIPTION

Top

This class provides a read method for catalogs written in a format used by the old ukstar web interface to the SAO and Bright Star catalogues. It is probable that this format has a real name and is a historical format rather than a UKIRT-specific format but the history of ukstar and the associated catalogue files is not known to the author of this module.

_read_catalog

Parses the catalogue lines and returns a new Astro::Catalog object containing the catalog entries.

 $cat = Astro::Catalog::IO::JCMT->_read_catalog( \@lines );

No options are supported.

FORMAT

The catalog format uses fixed formatting (first column is column 1):
