The Seyfert line_5: galaxy has been selected for observation because it is line_6: known to have strong molecular emission in the nuclear regions. line_7: In conjunction with existing mm-line observations of CO, our proposed line_8: HST data will be used to study the physical properties of the line_9: molecular gas lying in the direct line of sight to the line_10: galactic nucleus and to attempt a measure of the rotational line_11: temperature of CO in the circumnuclear molecular clouds which line_12: are associated with star formation. Observation of Mg II line_13: will also be carried out for calibration purposes. line_14: Keywords - SEYFERT GALAXY, AGN, CO ABSORPTION ! ! end of abstract general_form_proposers: lname: BLADES fname: JOHN title: PI mi: C. inst: STSCI country: U.S.A. ! lname: HECKMAN fname: TIMOTHY mi: M. inst: STSCI AND JOHN HOPKINS UNIVERSITY country: U.S.A. ! lname: LEVSHAKOV fname: SERGEI mi: A. inst: PTI USSR ACADEMY OF SCIENCES country: U.S.S.R. ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: This program can be performed only on the HST because it line_2: requires UV observations with high spectral resolution line_3: on extragalactic targets. No other instrumentation line_4: available. ! question: 4 section: 1 line_1: Our estimates indicate that the UV continuum fluxes of line_2: NGC 1068 should produce count rates per diode per second of line_3: 0.047 in the first-order of the G160M grating at the expected line_4: positions of the CO (2,0) band at 1483A. We could obtain a line_5: good signal to noise ratio S/N = 30 in an exposure time of line_6: about 6 hours. Therefore, we would like to observe these line_7: galaxies in high dispersion with a view to identification of line_8: the (2,0) band of the fourth positive system of the CO line_9: molecule and to get information about the line profile. line_10: We estimate that for a S/N ratio 30:1 our 3 sigma equivalent line_11: width limit is 25 mA, for 1% uncertainty in the continuum line_12: placement. We anticipate the CO lines to have strengths line_13: of the order 50-100 mA, well above our detection limit. line_14: The TAC gave 10 hours to the program which initially had line_15: two targets. We shall spend the ten hours on NGC 1068. ! question: 6 section: 1 line_1: We are going to use IRAF/STSDAS software at the STScI, and line_2: our own analysis software. ! question: 8 section: 1 line_1: Blades is a member of the FOC IDT and is involved in several line_2: imaging programs. line_3: P2553: The Absorption Cross-Sections of Nearby Galaxies : line_4: Blades, Pettini & Bowen. line_5: P2638: Near ultraviolet spectrum of 0215+015 : line_6: Blades, Hunstead & Pettini. line_7: P2644: The environments of starburst galaxies : line_8: Norman, Heckman, Danly & Blades. line_9: P2563: SINS: The Supernova Intensive Study : line_10: Kirschner et al. line_11: None of these is related to the current proposal. The FOC line_12: GTO program should give important complementary data on the line_13: ultraviolet and optical morphologies of these two galaxies. ! question: 9 section: 1 line_1: New data-analysis procedures can be supplied by the PTI USSR line_2: Academy of sciences as well as research assistance during line_3: this project. ! !end of general form text general_form_address: lname: BLADES fname: JOHN mi: C. category: PI inst: STSCI addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: U.S.A. phone: 301-338-4805 telex: 6849101 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC1068 descr_1: H,515 pos_1: RA = 02H 42M 40.691S +/- 0.13S, pos_2: DEC = -00D 00' 48.52" +/- 2" equinox: 2000 pm_or_par: NO fluxnum_1: 1 fluxval_1: F-LINE(1500)=7.4+/-0.2E-14 ! ! end of fixed targets !
