Two exposure series are taken with line_3: the telescope moved between them to test the effects of PSF variability over line_4: the field. The target is a moderately crowded field in NGC 1850 in the LMC. line_5: PSF exposures are taken in NGC 188, in Proposal 3013. The PSF must be line_6: measured once per WF/PC SAT "campaign" or if the mirror position has changed line_7: or more than 7 days have passed since the last calibration. ! ! end of abstract general_form_proposers: lname: fname: WF/PC IDT inst: VARIOUS country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: A series of WFC exposures is taken with wide filters in visible line_2: and IR wavelength bands, at two telescope positions. PSFs are line_3: are determined separately in a field in NGC 188 in 3013. ! question: 4 section: 1 line_1: Instrument calibration. ! question: 5 section: 1 line_1: This is a SAT activity for which the prerequsites are that the camera line_2: be UV-flooded, if we are using a flood, and the final telescope focus line_3: and collimation be adopted. The secondary mirror position and tilt should line_4: should not be adjusted between the PSF exposures in NGC188 in 3013 and the main line_5: exposures in NGC 1850. ! question: 6 section: 1 line_1: Avoid the SAA for all exposures. ! question: 7 section: 1 line_1: These data will be analyzed at the WF/PC data analysis facilities. They will line_2: also be part of the ScI calibration data base and the numbers will be included line_3: in the WF/PC calibration report. ! !end of general form text general_form_address: lname: WESTPHAL fname: JAMES mi: A. category: PI inst: CALTECH ! lname: LIGHT fname: ROBERT category: CON inst: WFPC TEAM addr_1: BOWIE STATE UNIVERSITY addr_2: 14000 JERICHO PARK ROAD city: BOWIE state: MD zip: 20715 country: USA phone: 301-464-9624 ! lname: FABER fname: SANDRA category: CON inst: WFPC TEAM addr_1: BOWIE STATE UNIVERSITY addr_2: 14000 JERICHO PARK ROAD city: BOWIE state: MD zip: 20715 country: USA phone: 301-464-9624 ! lname: GUNN fname: JAMES mi: E. category: CON inst: PRINCETON UNIVERSITY addr_1: ASTROPHYSICAL SCIENCE addr_2: PEYTON HALL city: PRINCETON state: NJ zip: 08540 country: USA phone: 609-452-3802 ! lname: DANIELSON fname: G.
