These line_5: numbers will greatly improve our understanding of the interstellar medium. ! ! end of abstract general_form_proposers: lname: JURA fname: MICHAEL inst: UC, LOS ANGELES country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The observations will be in the echelle and G160M modes to acquire very line_2: high signal to noise measurements of weak, narrow interstellar lines. line_3: In particular, we will observe the weak, forbidden lines of O I and C II, line_4: and additional lines of CO. Very high signal to noise ratios are required line_5: because the lines are weak and because there are several clouds in line_6: essentially every line of sight. ! question: 4 section: 1 line_1: Ultraviolet observations are impossible from the ground. The previous line_2: Copernicus and IUE observations had inadequate spectral resolution and signal line_3: to noise. ! question: 7 section: 1 line_1: Data reduction will be performed using the HRS software at Goddard or, if line_2: possible, the software will be transported to UCLA. ! question: 10 section: 1 line_1: UCLA can provide VAX and SUN computers and extensive experience line_2: with reducing IUE data. We have an efficient departmental computer line_3: center for data reduction facilities. ! question: 13 section: 1 line_1: This work is to observe interstellar C II, CO and O I toward 8 stars line_2: within 1 kpc of the sun. The goal is to measure accurate abundances, line_3: densities and to probe molecule formation and line_4: depletion theories. ! !end of general form text general_form_address: lname: JURA fname: MICHAEL title: PROF. category: PI inst: UC, LOS ANGELES addr_1: ASTRONOMY DEPARTMENT addr_2: UCLA city: LOS ANGELES state: CA zip: 90024 country: USA phone: 213-825-4302 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: HD24760 name_2: EPSILON-PER descr_1: B0.5 V STAR pos_1: RA=3H57M51.2S+/-0.1S, pos_2: DEC=40D0'37"+/-1" equinox: 2000 pm_or_par: NO rv_or_z: V=+1 fluxnum_1: 1 fluxval_1: V=2.89, fluxval_2: B-V=-0.18 ! ! end of fixed targets !
