This line_7: is a UV specific problem that requires ST collecting area. A positive line_8: detection will produce a point on the rotation curve far into the galaxy halo, line_9: as well as crude information on the physical conditions of the halo gas. Each line_10: spectrum will also contain information on the gas distribution of our galaxy. ! ! end of abstract general_form_proposers: lname: BEAVER fname: EDWARD inst: UC, SAN DIEGO country: USA ! lname: BURBIDGE fname: E.

Scale from 19 mag and line_2: fnu~1/nu, which implies 0.021 c/s at 1400 A, 0.133 c/s at 2800 A. line_3: Expose 8 ks/obj H13 170 cts at 1400 A line_4: 2 ks/obj H27 270 cts at 2800 A. line_6: Monitor tube bkg. for 1 sec every minute, or at least at the beginning line_7: and the end of the observation for 20 sec. Take wavelength cal at the end of line_8: each grating position, since velocities are critical. line_10: Worry about 1.5 ct/s/diode from L-alpha over 3 diodes for 2KR sky in the case line_11: of faint targets and Vr < 3 diodes ~ 750 km/s. Use smaller hole for Vr 300 to line_12: 750 km/s.

Ground line_12: based observations are required prior to line_13: the ST observations to establish if the line_14: object is bright enough to observe. Please line_15: do not schedule any FOS observations of line_16: 0318-196 in the first 4 months of the Cycle. line_17: Please notify us approximately when the ST line_18: observations will be scheduled as soon as line_19: the long range schedule is available. We line_20: will notify the ST ScI approximately 1-2 line_21: months prior to the ST observations line_22: (according to the long range schedule) if line_23: the object is too faint to observe. ! question: 6 section: 1 line_1: The FOS grating mechanism does not repeat to 50 microns = 230 km/s, so for the line_2: best (~25 km/s) velocity accuracy, a WAVE internal spectrum is required. ! question: 12 section: 1 line_1: This program constitutes a scientific investigation that cannot be considered line_2: viable until 7 of the 10 targets have been observed. None of the data in this line_3: program should be made public until 1 year after the program becomes viable as line_4: a whole. ! question: 13 section: 1 line_1: UV FOS spectra are used to search for extended halos of gas in galaxies by line_2: using QSO absorption lines as the diagnostic light source. ! !end of general form text general_form_address: lname: BOHLIN fname: RALPH category: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: 0015+162 descr_1: QUASAR IN RICH CLUSTER OF GALAXIES OF SAME descr_2: Z pos_1: RA=0H 18M 32.04S +/-0.3", pos_2: DEC=+16D 29' 25.3" +/- 0.3", pos_3: PLATE-ID=N404 equinox: 2000 rv_or_z: Z=0.553 fluxnum_1: 1 fluxval_1: V=18.2 ! targnum: 2 name_1: 3C48 descr_1: QUASAR PROJECTED 42 KPC FROM NGC 598(SCD) pos_1: RA=1H 37M 41.30S +/- 0.3", pos_2: DEC=+33D 9' 34.6" +/- 0.3" equinox: 2000 rv_or_z: Z=0.37 fluxnum_1: 1 fluxval_1: V=16.2 ! targnum: 3 name_1: 0318-196 descr_1: QUASAR PROJECTED 60 KPC FROM NGC 130D(SBB) pos_1: RA=3H 20M 21.15S +/- 0.3", pos_2: DEC=-19D 26' 31.7" +/-0.3", pos_3: PLATE-ID=S547 equinox: 2000 rv_or_z: Z=0.104 comment_1: B-V=1.04 fluxnum_1: 1 fluxval_1: V=17.5 ! targnum: 4 name_1: 3C245 descr_1: QUASAR NEAR INTERGALACTIC HI CLOUD OF descr_2: SKRUTSKIE ET AL pos_1: RA=10H 42M 44.63S +/- 0.3", pos_2: DEC=+12D 3' 32.2" +/- 0.3", pos_3: PLATE-ID=N490 equinox: 2000 rv_or_z: Z=1.029 comment_1: B-V=0.46 fluxnum_1: 1 fluxval_1: V=17.29 ! targnum: 5 name_1: PKS1103-006 descr_1: QUASAR PROJECTED 61 KPC FROM NGC 3521(SBC) pos_1: RA=11H 6M 31.75S +/- 0.3", pos_2: DEC=-0D 52' 53.4" +/- 0.3" equinox: 2000 rv_or_z: Z=0.43 fluxnum_1: 1 fluxval_1: V=16.5 ! targnum: 6 name_1: Q1601.5+1747 descr_1: BURBIDGE 1985, AP.J, 288,82 QUASAR IN descr_2: HERCULES SPIRAL RICH CLUSTER descr_3: DIAM=6' pos_1: RA=16H 03M 43.92S +/- 0.3", pos_2: DEC=+17D 38' 49.7" +/- 0.3", pos_3: PLATE-ID=N444 equinox: 2000 rv_or_z: Z=0.034 comment_1: Z IS FOR HERCULES CLUSTER, Z=1.481 comment_2: FOR QSO; USE F(~NU)~1/NU TO SCALE comment_3: FLUX DATA fluxnum_1: 1 fluxval_1: V=18.5 ! targnum: 7 name_1: 3C66A descr_1: QSO PROJECTED 92 KPC FROM THE GALAXY descr_2: 3C66B pos_1: RA=2H 22M 39.55S +/- 0.3", pos_2: DEC=+43D 2' 8.1" +/- 0.3", pos_3: PLATE-ID=N196 equinox: 2000 rv_or_z: Z=0.444 comment_1: V IS VARIABLE FROM 15 TO 16 fluxnum_1: 1 fluxval_1: V=15.5+/-0.5 ! targnum: 8 name_1: ABELL2197-QSO descr_1: QUASAR IN ABELL 2197 SPIRAL RICH CLUSTER pos_1: RA=16H 27M 43.93S +/- 0.3", pos_2: DEC=+40D 47' 43.2" +/- 0.3" equinox: 2000 rv_or_z: Z=1.082 comment_1: B-R=0.0 fluxnum_1: 1 fluxval_1: R=18 ! ! end of fixed targets !
