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 SLA or PAL

documentation: http://www.starlink.ac.uk/star/docs/sun67.htx/sun67.html

(in particular the palObs routine).

Requirements

------------

This class uses Astro::PAL which can be installed directly from CPAN.

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.minorplanetcenter.net/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.

Changes

-------

  v0.71 - Switch to using Astro::PAL

  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
