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.
