Using astrometry from that PC image, we now wish line_4: to take a UV FOS spectrum of the likely counterpart (called line_5: star S) using the G160L grating. An offset star will be line_6: acquired first, and then a blind pointing (based on line_11: the PC image astrometry) will be performed to star S. ! question: 4 section: 1 line_1: HST is essential, because of the need for spatially-resolved line_2: UV spectra in the corwded globular cluster core. ! ! question: 9 section: 1 line_1: All FOS IDT (GTO and AUG) data. ! question: 10 section: 1 line_1: Data analysis, research assistant support, and funding will line_2: be provided under NASA's FOS GTO contract(s). ! !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: 17 name_1: NGC6712-OFFSET descr_1: A,139 pos_1: RA = 18H 53M 04.97S +/- 0.01S, pos_2: DEC = -08D 42' 18.2" +/- 0.3" equinox: 2000 comment_1: E(B-V) FOR THE CLUSTER IS 0.48. comment_2: SPECTRAL TYPE IS G (IF IN comment_3: CLUSTER) OR K (IF FOREGROUND). fluxnum_1: 1 fluxval_1: V = 16.00 +/- 0.05 fluxnum_2: 2 fluxval_2: B = 17.00 +/- 0.05 fluxnum_3: 3 fluxval_3: U = 17.54 +/- 0.05 ! targnum: 28 name_1: NGC6712-STAR name_2: STAR-S descr_1: A,165 pos_1: RA-OFF = -0.13S +/- 0.01S, pos_2: DEC-OFF = -2.31" +/- 0.1", pos_3: FROM 17 equinox: 2000 acqpr_1: COMP fluxnum_1: 1 fluxval_1: B = 20.9 +/- 0.5 ! ! end of fixed targets !
