Astro::Coords

=============

This module provides an object oriented approach to astronomical

coordinate transformations. It can be used to convert between

J2000, B1950, Galactic and super Galactic coordinates.  It can

calculate the azimuth and elevation of a source specified in

equatorial coordinates, orbital elements or by name (if a planet).

It can also determine whether the specified coordinates are observable

for the given telescope and determine rise and set times. Doppler

corrections can also be calculated.

This software is still a beta release but is in use in a production

environment. The interfaces may still change slightly.

It is a wrapper class around Astro::PAL that simplifies the handling of

astronomical coordinate systems.

Requirements

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

This class uses Astro::PAL, Astro::Telescope as well as

DateTime and Time::Piece.

This release begins the migration from Time::Piece to DateTime

for specification of epochs. Both are supported at present but

at some point Time::Piece support may be removed.

Building

--------

  perl Build.PL

  ./Build

  ./Build test

  ./Build install
