The GTO program for the globular cluster systems line_4: involves WF/PC or FOC images to locate candidates for cluster X-ray sources line_5: (selection based on UV-excess in multicolor HST images), followed by confirming line_6: FOS spectroscopy. Even 1 or 2 new close binaries identified line_7: through this program will be extremely important, as these line_8: systems are thought to dominate the kinetic energy budget of line_9: globular clusters, yet virtually none are currently known. line_10: This program is for WFPC images of NGC6441. ! ! end of abstract general_form_proposers: lname: MARGON fname: BRUCE inst: UNIVERSITY OF WASHINGTON country: USA ! lname: HARMS fname: RICHARD title: PI mi: J. inst: APPLIED RESEARCH CORPORATION country: USA ! lname: BOHLIN fname: RALPH inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! lname: ANGEL fname: J.

If identical guide stars happen to be line_3: available for both observations, FOS acquisition could be line_4: significantly faster and more reliable. If not, we will offset from line_5: an arbitrary anonymous bright star in field, selected from the line_6: WFPC image. ! 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). The FOS IDT support includes a total of roughly line_3: 30 Ph.D. astronomers and graduate students at 5 different institutions. At line_4: each institution one or more workstations (typically Sparc 2's or the line_5: equivalent), plus one or more Microvaxes (or equivalent) are essentially line_6: devoted to processing of HST data. ! !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: 1 name_1: NGC6441 descr_1: C,201,A,165 pos_1: RA=17H 46M 48.5S+/-0.1S, pos_2: DEC=-37D 02' 17.8"+/-0.6" equinox: 1950 comment_1: GLOBULAR CLUSTER WITH comment_2: X-RAY SOURCE. fluxnum_1: 1 fluxval_1: SURF(V) = 14.0 +/-3.0 ! ! end of fixed targets !
