Astro::Catalog module --------------------- What is it? ----------- The module is a generic object orientated astronomical catalogue object. Requirements ------------ The madatory requirement of the Astro::Catalog package are, Astro::Coords Astro::Telescope Time::Piece File::Spec Math::Libm Net::Domain LWP::UserAgent SOAP::Lite Test Test::More Data::Dumper Carp Astro::VO::VOTable Astro::Flux Number::Uncertainty Misc::Quality See http://heasarc.gsfc.nasa.gov/classx/votable/index.html to obtain the GSFC Astro::VO::VOTable package. You need V0.9 or later of this module. Provides -------- The package provides the following user level classes Astro::Catalog A generic catalogue object, includes pluggable I/O support. Astro::Catalog::Item A generic catalogue item. NB: Astro::Catalog::Star is maintained for backwards compatibility. The following classes can be used to query various online databases for astronomical objects. They all return an Astro::Catalog object populated with matching Astro::Catalog::Star objects. Astro::Catalog::Query::2MASS Queries the Two Micron All Sky Survey (2MASS) catalogue. Astro::Catalog::Query::CMC Queries the Carlsberg Meridian Catalogue (CMC/12). Astro::Catalog::Query::GSC Queries the Guide Star Catalog (GSC). Astro::Catalog::Query::MPC Queries the Minor Planet Center database for solar system objects. Astro::Catalog::Query::Sesame Queries the CDS Sesame web service. Astro::Catalog::Query::SIMBAD Queries the CDS SIMBAD database. Implements most of the functionality of the Astro::SIMBAD module. Astro::Catalog::Query::SkyCat Queries SkyCat catalogues. For some catalogue queries, parsing of the returned catalogue will not work. In some cases the URLs of the resources may break this module's parsing code. Astro::Catalog::Query::SuperCOSMOS Queries the SuperCOSMOS catalogue. Astro::Catalog::Query::USNOA2 Queries the USNO-A2.0 catalogue. Astro::Catalog::Query::Vizier Queries Vizier catalogues. For some catalogue queries, parsing of the returned catalogue will not work. Additional classes provided by the package handle things that you don't need to concern yourself with, unless you want to write your own I/O or query plugins, these are Astro::Catalog::IO::Astrom (write only) Astro::Catalog::IO::ASSM (read only) Astro::Catalog::IO::Binary (read only) Astro::Catalog::IO::Cluster Astro::Catalog::IO::FINDOFF Astro::Catalog::IO::FITSTable Astro::Catalog::IO::GaiaPick (read only) Astro::Catalog::IO::JCMT Astro::Catalog::IO::LCOGFITSTable Astro::Catalog::IO::Northstar (read only) Astro::Catalog::IO::RITMatch Astro::Catalog::IO::SExtractor (read only) Astro::Catalog::IO::STL (read only) Astro::Catalog::IO::Simple Astro::Catalog::IO::TST (read only) Astro::Catalog::IO::UKIRTBS (read only) Astro::Catalog::IO::VOTable Astro::Catalog::IO::XY Astro::Catalog::Transport::REST Astro::Catalog::Transport::WebService Astro::Catalog::Query Astro::Catalog::Item::Morphology The user level query classes inherit from the Astro::Catalog::Transport::XXX classes, which in turn all inherit basic functionality from the Query base class Astro::Catalog::Query. The Astro::Catalog::IO modules provide pluggable polymorphic input/output. It should be noted that Astro::Catalog::IO::TST, STL, GaiaPick, SExtractor, and UKIRTBS do not currently provide a _write_catalog() function, and Astrom does not currently provide a _read_catalog() function. Where can I get it? ------------------- The package is available from CPAN and from github at https://github.com/timj/perl-Astro-Catalog Installation ------------ Installation is automated using the Module::Build library % perl Build.PL % ./Build % ./Build test % ./Build install Authors ------- The module was originally written by Alasdair Allan , of the University of Exeter Astrophysics Group (http://www.astro.ex.ac.uk/) as part of his work for the eSTAR project. The internal architecture of the module was extensively rewritten for v3.0 by Tim Jenness of the Joint Astronomy Centre in Hawaii and Alasdair Allan , of the University of Exeter Astrophysics Group. Then rewritten again by Alasdair Allan for the v4.0 release. This version also includes patches supplied by Stephen Quinney of Durham University, Tim Lister of Las Cumbres Observatory, and Luca Rizzi and Brad Cavanagh of the Joint Astronomy Centre in Hawaii.
