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.
