The PC will be on the cluster center; all 4 chips will be used. The photometry will reach at least to V = 26. Questions ! Free format text (clear and concise) Observing_Description: The program takes 9 orbits. Of these, 3 1/2 use F606W and 4 use F814W. Each of these orbits has two long exposures (the half orbit having only 1), and some shorter exposures are thrown in, to deal with stars that saturate in the longer exposures. F439W is used for 1/2 orbit and F336W for 1 orbit. Real_Time_Justification: N. A. Calibration_Justification: N. A. Additional_Comments: The whole program can be taken on a single GSACQ. The PC is aware that there is a 9-orbit visit and believes it is OK. See visit-level comment. Fixed_Targets !
