This report describes a General Unwanted Energy Rejection Analysis Program GUERAP. In addition to being a users guide for the program, the report presents the theory behind the program. A deterministic approach to stray light computation is presented in terms of 1 Differential ray trace methods 2 A ray theory of diffraction 3 A set of perturbative view factor matrices which allow the more important stray light effects to be calculated first. Some experimental verification of the calculated results is presented, as well as a description of how to use the program.
