World Coordinate Systems
The AST library provides a comprehensive range of facilities for attaching world coordinate systems to astronomical data, for retrieving and interpreting that information in a variety of formats, including FITS-WCS, and for generating graphical output based on it.
This programmer’s manual should be of interest to anyone writing astronomical applications which need to manipulate coordinate system data, especially celestial or spectral coordinate systems. AST is portable and environment-independent.
This is the Fortran version of this document.
For the C version, please see SUN/211.
