The line_5: magnitude and exposure length are chosen to give a good S/N line_6: without exceeding the count rates that are linear. ! ! end of abstract general_form_proposers: lname: PARESCE fname: FRANCESCO inst: STSCI country: USA esa: X ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Although the FOC UV filters are the best that technology line_2: can provide, their transmissions go down only to 10**(-3) line_3: or 10**(-4) at visible wavelengths. For many objects, line_4: these filters will give more counts through the redleak line_5: than in their main passband. This program will observe a line_6: G star through all the UV filters, and transmission at line_7: a number of wavelengths from 300 to more than 600 nm will line_8: be measured. Filters listed as priority 1 are expected to line_9: have bad redleaks and much use. Priority 3 are expected line_10: to have little or no redleak, but might have changed with line_11: time ! question: 5 section: 1 line_1: Only SV Minimum Plan filters are included in this proposal. line_6: Prerequisites: FOC Objective Prism Calibration (Test line_7: FOC-12a, 1519) completed. ! !end of general form text general_form_address: lname: PARESCE fname: FRANCESCO title: DR. category: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA phone: 301-338-4823 telex: 684-9101-STSCI ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: H-468 name_2: GSC-0180001935 descr_1: 9TH-MAG STAR descr_2: IN PLEIADES pos_1: RA = 03H 47M 10.03S +/- 0.1S, pos_2: DEC = +24D 16' 36.48" +/- 1", pos_3: PLATE-ID=009M equinox: 2000 pm_or_par: NO plate_req: NO ! ! end of fixed targets !
