GHRS Instrument Science Report 064 "Locate=Extended: A New Capability for GHRS" Stephen J. Hulbert and Wayne E. Baggett An abstract excerpted from the report: GHRS proposal 5591 was designed to test the new commanding capability known as LOCATE=EXTENDED. This capability is meant to improve the centering of extended targets in the GHRS X-direction. The test executed nominally although an incorrect use of the POS TARG special requirement in the proposal specification degraded some of the data. Supplemental use of pointing data demonstrated that the new commanding functioned nominally. No significant differences in centering were found for the target, Io, among the various modes of LOCATE=EXTENDED.
