This is a summary of the GHRS calibrations in Cycle 6, both routine monitoring programs and a special measurement of GHRS sensitivity without the COSTAR mirrors. A description of the programs and their scheduling requirements is given. This plan will require 22 external HST orbits and 60 internal orbits.
