If no interesting line_3: candidates are found, no followup spectra will be taken. If line_4: an interesting looking candidate is found, then spectra will line_5: be obtained, with the specific gratings to be used determined line_6: by the quality of the candidate. ! question: 3 section: 2 line_1: Cycle...Exposures....Object line_3: ..SAT.....26-29......NGC 6402 line_4: ..1.......30-33......NGC 6093 line_6: ..0.......42-45......NGC 6712 line_7: ..1.......34-37......NGC 104 line_9: ..2.......14-17......NGC 5824 line_10: ..2.......18-21......NGC 5139 line_11: ..2.......50-53......NGC 6624 line_12: ..2.......54-57......NGC 7078 line_13: ..2.......46-49......NGC 1851 line_14: ..2.......22-25......NGC 6656-C line_16: ..3.......38-41......NGC 6441 ! question: 5 section: 1 line_1: The SV prerequisite programs for all FOS observations in line_2: this program are: line_4: Prop ID 2195..FOS Target Acquisition Tests...All Observations line_5: Prop ID 1318..Spectral Flat Fields...........1st target line_6: Prop ID 1320..Absolute Spectrophotometry.....1st visit line_8: The WFC and PC exposures MUST be obtained AFTER the UV flood. line_10: We will need to set the REJLIM parameter based on the true line_11: magnitude of the candidate star obtained from the PC images. ! question: 7 section: 1 line_1: Data reduction will be performed at the ST ScI, and the analysis will be line_2: performed using FOS IDT computer facilities. ! question: 8 section: 1 line_1: Candidates for spectroscopy will all appear in WF/PC images. If identical line_2: guide stars are available for both observations, FOS acquisition could be line_3: significantly faster and more reliable. If not, we will offset from arbitrary line_4: anonymous bright stars in field. ! question: 10 section: 1 line_1: Data analysis, research assistant support, and funding will be provided under line_2: NASA's FOS GTO contract(s). ! question: 12 section: 1 line_1: Completion of the scientific goals of this program requires the intercomparison line_2: of data on the majority of separate objects. Thus, these goals will not be line_3: fulfilled until at least 80% of the targets have been observed. line_5: The total estimated observing time on the cover sheet assumes that 65% of the line_6: fields with image will yield candidates requiring spectroscopy; thus, actual line_7: time will probably be less. If candidates are found, spectra should be line_8: scheduled within 75+/-15 days of the delivery of the WF/PC data to the PI. ! question: 13 section: 1 line_1: Multicolor WF/PC images will be used to search for the optical counterparts of line_2: both central and noncentral X-ray sources. Objects identified through unusual line_3: colors will be observed with the FOS. The recovery of two historical novae in line_4: globular clusters, and spectra to yield abundances and possibly expansion line_5: parallaxes, is also proposed. ! !end of general form text general_form_address: lname: MARGON fname: BRUCE category: PI inst: UNIVERSITY OF WASHINGTON addr_1: ASTRONOMY DEPARTMENT, FM-20 city: SEATTLE state: WA zip: 98195 country: USA phone: 206 543-0089 telex: 4740096 ! ! end of general_form_address records fixed_targets: targnum: 6 name_1: NGC6712 descr_1: GLOBULAR CLUSTER WITH CENTRAL X-RAY SOURCE pos_1: RA=18H 50M 21.2S+/-0.1S, pos_2: DEC=-08D 46' 04.4"+/-0.4" equinox: 1950 fluxnum_1: 1 fluxval_1: SURF(V) =18.8+/- 0.5 ! targnum: 17 name_1: NGC6712-OFFSET descr_1: OFFSET STAR pos_1: TBD-EARLY, pos_2: RA=18H 50M 21.2S+/-1.5S, pos_3: DEC=-08D 46' 04.4"+/-20" equinox: 1950 fluxnum_1: 1 fluxval_1: V = 15 +/- 3 ! targnum: 28 name_1: NGC6712-STAR descr_1: CENTRAL X-RAY SOURCE IN GLOBULAR CLUSTER pos_1: TBD-EARLY, pos_2: RA-OFF = 0S +/- 1.5S, pos_3: DEC-OFF = 0" +/- 20", pos_4: FROM 17 equinox: 1950 acqpr_1: COMP fluxnum_1: 1 fluxval_1: V = 18 +/- 3 ! ! end of fixed targets !
