Six line_3: exposures in six filters in both the WF and PC are line_4: taken of a UV flux standard star. The total duration line_5: is two orbits. The program should be repeated every line_6: four weeks. Along with the internal line_7: monitor program, this stellar monitor comprises the line_8: regular monitoring program for the throughput and line_9: focus of the WFPC and should start to be scheduled line_10: when the initial calibration programs cease, that is, line_11: in late Mar. or April 1991. ! ! end of abstract general_form_proposers: lname: fname: WF/PC IDT inst: VARIOUS ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: A single exposure is taken in six broad-band filters line_2: from F194W to F785LP using a UV flux standard star. line_3: For economy, only W2 and P6 are used, making 12 exposures line_4: in all. The UV stars are bright, and the exposures are line_5: fairly short. ! question: 5 section: 0 line_1: This program should be part of the SV minimum plan. line_2: It should be carried out regardless of the state of line_3: the UV flood. ! question: 6 section: 1 line_1: Flux standards are needed to monitor throughput. line_2: This program overlaps slightly with the PSF monitor line_3: proposal. However, PSF monitor is a line_4: smaller proposal through visible filters only that line_5: monitors PSF stability only on timescales line_6: of a week. The present stellar monitor covers throughput line_7: and PSF over a much wider range of wavelengths, however less line_8: frequently. After more experience on orbit, these two line_9: proposals may be revised and combined to be maximally line_10: efficient. ! question: 7 section: 1 line_1: These data will be archived at ScI and the numbers included in the WF/PC line_2: calibration report. ! !end of general form text general_form_address: lname: WESTPHAL fname: JAMES mi: A. category: PI inst: CALTECH ! 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) 452-3802 ! lname: DANIELSON fname: G. mi: E. category: CON inst: CALTECH addr_1: M/S 170-25 addr_2: DIVISION OF GEOLOGICAL & PLANETARY SCIENCES city: PASADENA state: CA zip: 91125 country: USA phone: (818) 356-6861 ! lname: CODE fname: ARTHUR mi: D. category: CON inst: UNIVERSITY OF WISCONSIN addr_1: SPACE ASTRONOMY LABORATORY addr_2: 1150 UNIVERSITY AVENUE city: MADISON state: WI zip: 53706 country: USA phone: (608) 262-9594 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: BD+28D4211 descr_1: FLUX STANDARD pos_1: RA = 21H 51M 11.07S +/- 1S, pos_2: DEC = +28D 51' 51.8" +/- 1" equinox: 2000. fluxnum_1: 1 fluxval_1: V=10.51 ! targnum: 2 name_1: BD+75D325 descr_1: FLUX STANDARD pos_1: RA = 08H 10M 49.31S +/- 1S, pos_2: DEC = +74D 57' 57.5" +/- 1" equinox: 2000. fluxnum_1: 1 fluxval_1: V=9.54 ! targnum: 3 name_1: A+81D266 name_2: GSC4547-1009 descr_1: UV STANDARD pos_1: RA = 09H 21M 19.06S +/- 1S, pos_2: DEC = +81D 43' 28.6" +/- 1", pos_3: PLATE-ID=00LN equinox: 2000. fluxnum_1: 1 fluxval_1: V = 11.92 ! ! end of fixed targets !
