Typical line_3: S/N will be about 20. line_5: CYCLE 0 : EXPOSURES 1-16;CYCLE 1:EXPOSURES 17-22 line_6: for GHRS observations coarse track lock only is required ! question: 4 section: 1 line_1: The absorption lines in question are in the UV and cannot be observed from the line_2: ground. The combination of high resolution and high S/N require the line_3: sensitivity of ST. ! question: 7 section: 1 line_1: Data reduction and subsequent analysis will be carried out using the line_2: facilities of OCIW. ! question: 10 section: 1 line_1: The normal reduction and analysis facilities of OCIW line_2: will support this project. Some additional line_3: support for peripheral equipment and manpower is anticipated through contract line_4: to the PI through NASA GTO contracts. ! question: 12 section: 1 line_1: The total exposure time listed in item 9 on the cover page includes the line_2: estimated overhead for target acquisition, Pt-Ne lamps, grating settling time line_3: and stow time. ! question: 13 section: 1 line_1: HRS spectra of 3C273 will be obtained in the R=20000 mode over the range line_2: 1210-1425 A and at a selected longer wavelength to detect weak absorption line_3: lines. Detections or upper limits of low column density Lyman alpha clouds line_4: will be made and the profiles of the lines measured. Profiles of lines arising line_5: in the halo of the galaxy will also be obtained. ! !end of general form text general_form_address: lname: WEYMANN fname: RAY mi: J. title: DR. category: PI inst: CARNEGIE OBSERVATORIES addr_1: 813 SANTA BARBARA ST. city: PASADENA state: CA zip: 91101 country: USA phone: (818)304-0250 telex: 1561318 MWLCO UT ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: 3C273.0 name_2: PG1226+023 descr_1: BRIGHT LOW RED-SHIFT QUASAR pos_1: RA=12H 26M 33.35S +/- 0.5", pos_2: DEC=+02D 19' 42.4" +/- 0.5" equinox: 1950 rv_or_z: Z=0.158 comment_1: F-CONT FLUX FROM IUE DATA. fluxnum_1: 1 fluxval_1: V=12.8 +/- 0.3 fluxnum_2: 2 fluxval_2: F-CONT(1300)=3.5 +/- 0.5 E-13 fluxnum_3: 3 fluxval_3: F-CONT(2700)=1.2 +/- 0.2 E-13 ! ! end of fixed targets !
