Starlink::AST - Perl interface to Starlink's AST library ======================================================== This module provides a Perl interface to Starlink's AST library and 3 pluggable graphics backends that can be used in conjunction with the AST library. The AST library provides: - generic approach to attaching coordinate frames to data sets + if you have an array representing a spectrum in wavelength and another array that represents frequency, AST can resample one array to the other coordinate frame and allow you to add them together. This will work for any coordinate system so long as AST understands how to form the mapping. (many mappings are provided by default). - A generic plotting interface whereby you can + Have pluggable backends for the plotting system (currently PGPLOT, PLplot and Tk (or Tk::Zinc) canvas) + The ability to draw annotations, great circles and marks in a coordinate frame most useful to you (eg sky coordinate, a wavelength) and have AST map that directly to the underlying graphics coordinate system. REQUIREMENTS ------------ The module comes with the source code so no external libraries are required. For more information on AST see: http://www.starlink.ac.uk/ast INSTALLATION ------------ % perl Build.PL % ./Build % ./Build test % ./Build install NOTES ----- The Tk canvas interface does work with limitations. This is an early proof of concept release (although 95% of AST is supported and the PGPLOT and PLplot interfaces do work).
