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 Author ------ This module was written by Tim Jenness of the Joint Astronomy Centre.
