Astro::Telescope ================ This class can be used to retrieve and process details of particular telescopes. It can be used to determine the location and altitude of a telescope as well as the observational limits. The list of supported telescopes can be obtained from the SLALIB documentation: http://www.starlink.ac.uk/star/docs/sun67.htx/sun67.html (in particular the slaObs routine). Requirements ------------ This class uses Astro::SLA. In the future this dependency will be removed and the telescope tables will be kept internally. Modifying the MPC observatory code list --------------------------------------- To allow for Minor Planet Center observatory code use, this module uses a data file containing the MPC observatory code, longitude, and parallax coefficients for a large number of observatories. This data file resides in tmpl/MPC.dat and a new version can be obtained from http://www.cfa.harvard.edu/iau/lists/ObsCodes.html. To use an updated version, copy the information from that page (only the data, not any of the headers) into tmpl/MPC.dat, then build this module again. This will automatically create Telescope/MPC.pm, which can then be installed as part of this module. Building -------- perl Makefile.PL make make test make install The test make sure some simple parameters can be obtained and that limits work as expected. Authors ------- This module was written by Tim Jenness of the Joint Astronomy Centre. Updates have been supplied by Brad Cavanagh of the Joint Astronomy Centre.

Changes ------- v0.70 - Now uses Module::Build - MPC functionality available without requiring Astro::SLA - Default limits of the horizon for observability - setlimits() method can now be used to set observability limits. v0.60 - Updates for MPC observatory codes and related information. Can now instantiate an object with specified coordinates. v0.50 - First release to CPAN
