Measurement of the spin temperature and column depth will allow us line_3: to discriminate between different models for the absorbing gas. ! ! end of abstract general_form_proposers: lname: COHEN fname: ROSS inst: UC, SAN DIEGO country: USA ! lname: BEAVER fname: EDWARD inst: UC, SAN DIEGO country: USA ! lname: MARGON fname: BRUCE inst: WASHINGTON, UNIVERSITY OF country: USA ! lname: DAVIDSEN fname: ARTHUR mi: F. inst: JOHNS HOPKINS UNIVERSITY country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: We will use the FOS at low resolution to determine which of three quasars line_2: with known 21-cm absorption have light at the wavelength of L-alpha in the line_3: absorption system. For those with enough light, we will make high resolution line_4: FOS exposures-(S/N 10-20) of the L-alpha region. line_6: Cycle 1: Exposures 1-2 (3C286),Exposures 6-8 (PKS1229-021), line_7: and Exposures 11-13 (3C196); Cycle 2: Exposures 4-5 (3C286), line_8: Exposures 9-10 (PKS1229-021), Exposures 14-15 (3C196) ! question: 4 section: 1 line_1: These measurements have been made in only one ground based object. line_2: Three additional objects are available where spin temperature and column line_3: depth in a quasar absorption line cloud can be made using UV observations. ! question: 5 section: 1 line_1: The absorption lines occur short of L-alpha in the quasar, where the amount of line_2: light is generally unknown. Decisions will be made on whether or not to make line_3: high resolution observations after the appropriate low resolution observations line_4: are made. Exposure times may need to be varied. There cannot be too much time line_5: between low and high resolution observations because of the possibility of line_6: variations. ! question: 7 section: 1 line_1: Data will be reduced and analyzed on a UCSD VAX computer. ! question: 8 section: 1 line_1: We will try to arrange for new 21-cm observations within a few months of the line_2: UV observations. ! question: 10 section: 1 line_1: All data analysis will be done on UCSD equipment. ! question: 13 section: 1 line_1: Three quasars with 21-cm absorption will be observed at L-alpha to determine HI line_2: column depth and spin temperatures in the absorbing gas. ! !end of general form text general_form_address: lname: COHEN fname: ROSS category: CON inst: UNIV.
