It is possible that this phenomenon line_8: is related to the "breathing" of the secondary mirror. ! question: 3 section: 1 line_1: The test consists of two parts each of three phases: line_2: PART 1: Object in the plane of the orbit line_3: Phase 1: a series of ACCUMs in the SSA line_4: Phase 2: a series of IMAGES in the LSA line_5: Phase 3: a series of ACCUMs in the SSA line_6: PART 2: Object in CVZ line_7: Phase 1: a series of ACCUMs in the SSA line_8: Phase 2: a series of IMAGES in the LSA line_9: Phase 3: a series of ACCUMs in the SSA ! question: 5 section: 1 line_1: Exposure times are dictated by need to monitor with line_2: one minute time resolution. The imaging of the LSA should line_3: take place over one orbit. Each series of ACCUMs should b line_4: also cover about one orbit. line_5: Addtional time is required for the onboard line_6: acquisitions. line_7: BD+60D2533 is in the CVZ and should be observed accordingly. ! !end of general form text general_form_address: lname: SODERBLOM fname: DAVID title: DR. category: PI inst: SPACE TELESCOPE SCIENCE INSTITIUE addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA ! lname: BELY fname: PIERRE title: DR. category: CON inst: SPACE TELESCOPE SCIENCE INSTITIUE addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA ! lname: HULBERT fname: STEPHEN title: DR. category: CON inst: SPACE TELESCOPE SCIENCE INSTITIUE 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: HD333282 name_2: BD+28D3562 name_3: GSC2153-834 descr_1: J,704,707 pos_1: RA = 19H 59M 30.99S +/- 0.1S, pos_2: DEC = 29D 20' 09.4" +/- 0.2", equinox: 2000 pm_or_par: N pos_epoch_bj: J pos_epoch_yr: 2000.00 ra_pm_val: 0.000688 dec_pm_val: -0.0130 rv_or_z: V=40 comment_1: SPECTRAL TYPE=B7III comment_2: AGK+292199 fluxnum_1: 1 fluxval_1: V=9.89 fluxnum_2: 2 fluxval_2: B-V=+0.31 ! targnum: 2 name_1: BD+60D2533 name_2: AGK+60D1562 name_3: GSC4279-975 descr_1: J,704,707 pos_1: RA = 23H 24M 33.02S +/- 0.1S, pos_2: DEC = 61D 09' 28.3" +/- 0.2", equinox: 2000 pm_or_par: N pos_epoch_bj: J pos_epoch_yr: 2000.00 ra_pm_val: 0.000276 dec_pm_val: -0.0040 rv_or_z: V=26 comment_1: SPECTRAL TYPE=B9III comment_2: IN THE CVZ fluxnum_1: 1 fluxval_1: V=8.967 fluxnum_2: 2 fluxval_2: B-V=0.111 ! ! end of fixed targets !
