The Space Interferometry Mission (SIM) will make precise astrometricmeasurements that can be used to detect planets around nearby stars. Sinceobservational time will be extremely valuable, it is important to consider howthe choice of the observing schedule influences the efficiency of SIM planetsearches. We have conducted Monte Carlo simulations of astrometric observationsto understand the effects of different scheduling algorithms. We find that theefficiency of planet searches is relatively insensitive to the observingschedule for most reasonable observing schedules.Comment: 29 pages, 9 figures, 2 tables, to be published in PAS
