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. line_8: Cycle...Exposures....Object line_9: ..1.......10-12......NGC 104 ! question: 5 section: 1 line_1: 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. ! !end of general form text general_form_address: lname: MARGON fname: BRUCE category: PI inst: WASHINGTON, UNIVERSITY OF ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC104 name_2: 47-TUC descr_1: GLOBULAR CLUSTER WITH CENTRAL X-RAY SOURCE pos_1: RA =00H 21M 58.2S+/-0.1S, pos_2: DEC = -72D 21' 24.6"+/-1" equinox: 1950 fluxnum_1: 1 fluxval_1: SURF(V) = 14.4 +/-0.5 ! targnum: 2 name_1: NGC104-OFFSET descr_1: OFFSET STAR pos_1: TBD-EARLY, pos_2: RA=00H 21M 51.6S+/-0.5S, pos_3: DEC= -72D 21' 34.6"+/-5" equinox: 1950 fluxnum_1: 1 fluxval_1: V = 15 +/- 3 ! targnum: 3 name_1: NGC104-STAR descr_1: CENTRAL X-RAY SOURCE IN GLOBULAR CLUSTER pos_1: TBD-EARLY, pos_2: RA-OFF = 0S +/- 1.10S, pos_3: DEC-OFF = 0" +/- 5", pos_4: FROM 2 equinox: 1950 acqpr_1: COMP fluxnum_1: 1 fluxval_1: V = 18 +/- 3 ! ! end of fixed targets !
