Detailed Description

Spherical Transform Definition.

We need to be able to convert between ICRS, Galactic and Ecliptic coordinates, and potentially between arbitrary spherical coordinate systems. All of these basic spherical transformations represent rotations of the spherical coordinate reference. We specify a general transformation function which takes a structure, psSphereTransform, defining the transformation between two spherical coordinate systems
