GHRS Instrument Science Report 050 "SSA PEAKUP Test - Part 1" 7/93 Stephen J. Hulbert, Joseph P. Skapik and Wayne E. Baggett Abstract excerpted from the report: This report summarizes the results of the first test of the new SSA ACQ/PEAKUP commanding capability. This technique will allow us to properly center an object in the SSA. The test had mixed results:the return-to-brightest point algorithm worked properly but the GHRS was looking at the wrong aperture during the PEAKUP.
