TRANSFORM — Coordinate Transformation Facility
Programmer’s Guide and Reference Manual
TRANSFORM provides a standard, flexible method for manipulating coordinate transformations and for transferring information about them between applications. It can handle coordinate systems with any number of dimensions and can efficiently process large (i.e. image-sized) arrays of coordinate data using a variety of numerical precisions. No specific support for astronomical coordinate transformations or map projections is included – these features are provided by the AST library.
