A crowded field in Omega Cen line_4: will be observed. The first execution will be six to line_5: eight weeks after launch. The test may be repeated every line_6: eight weeks, should the need arise. ! ! end of abstract general_form_proposers: lname: HASAN fname: HASHIMA inst: ST SCI country: USA ! lname: BURROWS fname: C. inst: ESA/ST SCI country: USA esa: X ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: line_3: A set of up to 10 images will be taken using the WFPC2 line_4: with filter F555W over one orbital period. line_5: The test may need to be repeated, should the need line_6: arise. The target will be field in Omega Cen. The line_7: number of images can be reduced if observation exceeds line_8: one orbit. ! question: 4 section: 1 line_1: The observations will provide data useful in assessing the line_2: HST OTA Focal plane desorption as well as OTA line_3: breathing. ! !end of general form text general_form_address: lname: HASAN fname: HASHIMA category: PI inst: ST SCI addr_1: 3700 SAN MARTIN DR city: BALTIMORE state: MD zip: 21218 ! lname: BURROWS fname: C. category: CON inst: ESA addr_1: 3700 SAN MARTIN DR city: BALTIMORE state: MD zip: 21218 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: OMEGA-CEN descr_1: J,702 pos_1: RA = 13H 25M 37.04S +/- 0.1S, pos_2: DEC = -47D 35' 38.3" +/- 1.0" equinox: 2000 fluxnum_1: 1 fluxval_1: V=14.5 ! ! end of fixed targets !
