Astro::PAL -- interface to Starlink PAL C library ========== This module provides an interface layer to the Starlink PAL positional astronomy library. An example program, stime, is provided. This simply reports the current time (modified Julian day and local sidereal time for the JCMT). Requirements: ------------- A C compiler is required but the SOFA and PAL source code are included with the distribution and will be built automatically. Installation: ------------- % perl Build.PL % ./Build % ./Build test % ./Build install The tests only test part of the build. Some functions remain untested. See Astro::Coords for a general object-oriented wrapper around Astro::PAL. Documentation: -------------- The module provides documentation on how to use the perl interface to PAL. It does not contain information on how to use PAL itself. The basic PAL documentation can be found at http://www.starlink.ac.uk/star/docs/sun267.htx/sun267.html For more information the SLA documentation provides much more detail: http://www.starlink.ac.uk/star/docs/sun67.htx/sun67.html Copyright --------- Copyright (C) 2012 Tim Jenness and the Science and Technology Facilities Council.
