Ground-based measurements of these fields have been made with a line_6: detector and filter set identical to the WF/PC. line_8: Revised 11/8/89 by PStanley to correct Cycle 0 line list. line_9: Revised 1/9/90 by PStanley to expand out SEQ to avoid AFTER conflicts line_10: during transformation. ! ! end of abstract general_form_proposers: lname: fname: WF/PC IDT inst: VARIOUS country: USA ! lname: WESTPHAL fname: JAMES mi: A. inst: CALIFORNIA INSTITUTE OF TECHNOLOGY country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: line_4: In order to verify the scientific photometric line_5: measurement capabilities of each filter in the WF/PC and determine the spectral line_6: and spatial properties, all the filters will be used in this calibration. line_7: However, only a subset will be used to look at time variations and geometric line_8: stability measurements. The set of filters used to monitor the stability are: line_9: F555W, F785LP. Dark frames are grouped near each cluster visit. line_12: In order to reduce each of these observations, the appropriate external flat line_13: field calibrations will be required. ! question: 4 section: 1 line_1: Instrument calibration which is coordinated with the appropriate ground-based line_2: observations. ! question: 5 section: 1 line_1: SV Prerequisites: line_2: Activity start is defined as line 250 for WFC and line 271 for PC. line_3: Target Information: line_4: NGC 5139 is the preferred target and NGC 6752 is the alternate. ! question: 6 section: 1 line_1: This is a normal calibration observation. Since no exposure time exceeds 1000 line_2: seconds dark time scheduling is not required. ! question: 7 section: 1 line_1: These data will be part of the calibration data base at the ScI and will be line_2: used to determine the photometric sensitivity of each of the CCDs through each line_3: of the filters. These data will be analyzed by the WF/PC IDT. The output line_4: products will be published in the Calibrations Report whcih will be delivered line_5: to the ScI. ! question: 8 section: 1 line_1: Ground-based observations of these fields is essential to line_2: establish the absolute flux for each star. ! !end of general form text general_form_address: lname: WESTPHAL fname: JAMES mi: A. category: PI inst: CALTECH ! lname: DANIELSON fname: G. mi: E. inst: CALTECH M/S 170-25 addr_1: GEOLOGICAL & PLANETARY SCIENCES city: PASADENA state: CA zip: 91125 country: USA phone: (818) 356-6861 ! lname: GUNN fname: JAMES mi: E. inst: PRINCETON UNIVERSITY addr_1: ASTROPHYSICAL SCIENCE addr_2: PEYTON HALL city: PRINCETON state: NJ zip: 08540 country: USA phone: (609) 452-3803 ! lname: BAUM fname: WILLIAM mi: A. inst: LOWELL OBSERVATORY addr_1: PLANETARY RESEARCH CENTER addr_2: 1400 W.
