Module name: coordinate
Author: Ian Stewart (University of Leicester, ims@star.le.ac.uk)
This module contains subroutines to perform a variety of coordinate transformations. Where possible the cal coordinate-transformation routines are used. The present subroutines have been designed to act as wrappers-of-convenience for one or more of the cal routines rather than to supplant them.
