"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.
