convregion creates region descriptions in detector coordinates from input regions in RA and Dec. It operates in three modes where 1) FITS region input and output files are used, 2) ASCII file lists of region descriptors are both input and output, and 3) region descriptors for individual regions are input on the command line and output on the screen.
Warning and requirements: convregion was originally part of the package esas, integrated into SAS, but can be used as a general tool.
