Abstract:

This note describes a set of FORTRAN routines (REZEST) that calculates estimates of charged track resolution in transverse momentum and direction for the GlueX detector geometry. Parameters of that geometry can be varied to quickly obtain estimates for new configurations. Since no Monte Carlo is used in the calculations, results are returned immediately. Instructions on how to obtain and use the software are provided and a description of the approximations used is given.
