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://star-www.rl.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://cfa-www.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.

Can now instantiate an object with specified coordinates. v0.50 - First release to CPAN
