This field will be used for the SMOV line_3: FGS/GHRS coarse alignment after the deployment of COSTAR. line_4: Knowledge of the distribution of blue stars in this field line_5: will provide valuable information for the analysis of the line_6: coarse alignment test. ! ! end of abstract general_form_proposers: lname: SODERBLOM fname: DAVID title: DR. mi: R. inst: STSCI country: USA ! lname: HULBERT fname: STEPHEN title: DR. mi: J. inst: STSCI country: USA ! ! end of general_form_proposers block general_form_text: question: 2 section: 1 line_1: The FGS/GHRS coarse alignment test during SMOV will line_2: be used to locate the GHRS apertures in the focal plane. line_3: The test defined will carry out a series of spiral line_4: searches using the GHRS LSA to "map" out a "large" line_5: (16 x 16 arc sec) area on the sky in the cluster NCG 346. line_6: Comparison of the positions of known objects in each of line_7: the map pieces will allow the determination of the aperture line_8: location as well as a check on the parity of GHRS slews. line_9: The image obtained in this program will serve as an line_10: "early acq" of the part of the sky that GHRS will be line_11: observing during the coarse alignment test. ! question: 3 section: 1 line_1: A single wide field camera U band image will be line_2: obtained at the central position to be used in the line_3: coarse alignment test. ! question: 5 section: 1 line_1: Exposure time is based on the the V magnitudes of the line_2: brightest O stars in field: V=14.18. ! !end of general form text general_form_address: lname: SODERBLOM fname: DAVID mi: R. title: DR. category: PI inst: STSCI addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA ! lname: HULBERT fname: STEPHEN mi: J. title: DR. category: CON inst: STSCI addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC346 descr_1: J,701 pos_1: RA = 00H 59M 03.90S +/- 0.02S, pos_2: DEC = -72D 10' 41.4" +/- 0.2", equinox: 2000 pm_or_par: NO comment_1: BRIGHTEST STAR IN FIELD (O7). comment_2: AVERAGE E(B-V)=0.14 fluxnum_1: 1 fluxval_1: V=14.18 +/- 0.1 fluxnum_2: 2 fluxval_2: B-V=-0.23 +/- 0.05 ! ! end of fixed targets !
