A common target acquisition strategy with the Faint Object
Spectrograph (FOS) on board the Hubble Space Telescope (HST) is to use
a sequence of ACQ/PEAK stages. Standard sequences and exposure times
are given in the FOS Instrument Handbook (Keyes et al. 1995). The
success of a given strategy is difficult to predict a priori for
targets other than point sources. This paper describes a FORTRAN
program that simulates ACQ/PEAK acquisitions in a Monte-Carlo manner,
for a variety of targets. The software is available from the FOS
Instrument Scientists or from the author. It allows a proper
quantitative assessment to be made of whether an acquisition will
succeed, what exposure times should be used, and how the efficiency
can be optimized.
