The data will permit line_3: the calculation of commands for adjusting the secondary mirror line_4: to reduce the optical distortions. Mirror adjustments will be line_5: made to compensate for the changes in alignment. line_6: (Primary mirror adjustments are not anticipated.) line_7: NOTE: This proposal has been developed by CTA, Inc line_8: at the direction of Keith Kalinowski, line_9: HSTP-G. It is based on the OV/1 proposal submitted by line_10: P-E, whose PI and co-I's have been explicitly retained here. ! ! end of abstract general_form_proposers: lname: FACEY fname: T. inst: PERKIN-ELMER country: USA ! lname: BROWN fname: R. inst: PERKIN-ELMER country: USA ! lname: BRADY fname: W. mi: L. inst: PERKIN-ELMER country: USA ! lname: WINCHELL fname: D. mi: G. inst: PERKIN-ELMER country: USA ! ! end of general_form_proposers block general_form_text: question: 2 section: 0 line_1: This activity will provide data on the effects of desorption line_2: on the optical alignment of the telescope.

Mirror adjustments will be line_5: made to compensate for the changes in the alignment. line_6: (Primary mirror adjustments are not anticipated.) ! question: 3 section: 1 line_1: The desorption focus adjustment activity should be initiated 15 line_2: hours +/-3 hours after completion of the activity "Bootstrap line_3: Phase B/Wave Front Measurement and Adjustment" (PEP ID 2148). line_4: Two initial focus adjustment activities are conducted, line_5: separated in time by a nominal period of 18 hours. For each of line_6: these activities, the wavefront errors will be measured using line_7: the wavefront sensors in the Normal Mode. The errors determined line_8: from the Normal Mode test will be minimized by adjusting the line_9: Secondary Mirror. Following the initial two focus activities, line_10: the focus operations will alternate between one wherein line_11: only the secondary mirror is adjusted, and one wherein line_12: the wavefront errors are measured and then the secondary line_13: mirror is adjusted. These operations are started in OV line_14: and continued during SV. THIS PROPOSAL CONTAINS THE SV OBS. line_15: OF THIS TEST. The periodicity of the alternating line_16: focus operations, and the tolerance in the performance of line_17: these operations, will vary as a function of MET according line_18: to the following schedule; this schedule indicates the exp. line_19: logsheet line number corresponding to each focus operation. ! question: 3 section: 2 line_1: SV DAY 1 wavefront measurement and adjustment: lines 26.0-26.3 line_2: SV DAY 5.9 adjustment: line 27 line_3: SV DAY 11.4 wavefront measurement and adjustment: lines 28.0-28.3 line_4: SV DAY 17.6 adjustment: line 29 line_5: SV DAY 24.8 wavefront measurement and adjustment: lines 30.0-30.3 line_6: SV DAY 33.2 adjustment: line 31 line_7: SV DAY 43.3 wavefront measurement and adjustment: lines 32.0-32.3 line_8: SV DAY 55.7 adjustment: line 33 line_9: SV DAY 71.9 wavefront measurement and adjustment: lines 34.0-34.3 line_10: SV DAY 94.4 adjustment: line 35 line_11: SV DAY 130.6 wavefront measurement and adjustment: lines 36.0-36.3 ! question: 5 section: 0 line_1: Real-time telemetry for analysis and real-time commanding for line_2: OCE and FGS configuration and mirror adjustments. line_4: The desorption focus adjstment activity is started in OV/1 line_5: (proposal 2155), continued in OV/2 (proposal TBA after launch plus line_6: 30 days) and continued in SV (this proposal). The observations line_7: of this proposal start as early in SV as possible. ! question: 5 section: 2 line_1: The Astrometry Team will supply a special GSSS catalog of line_2: candidate guide stars for Iota Carina, HR6636, HR6850, and line_3: HR6945. Astrometry header data is required to be appended to line_4: Exposure Logsheet lines 11,and 12, to enable the data line_10: obtained from this activity to be used by the Astrometry line_11: Team in the evaluation of the OV Astrometry Test AST-OV-12. ! question: 7 section: 0 line_1: The wavefront sensor software resident in PASS will process the line_2: Normal Mode data for each wavefront sensor observation. The line_3: results of this processing for Wavefront Sensors #1 and #3 will line_4: be evaluated by the actuator control software resident in PASS line_5: and will generate the corresponding actuator command directives line_6: to move the Secondary Mirror. The actuator command directives line_7: will be displayed for operator verification or alteration. line_8: IT IS ESSENTIAL THAT THE REPOSITIONING THE SECONDARY MIRROR line_9: FOCUS THE TELESCOPE 0.25MM OUTSIDE OF THE NOMINAL FOCAL PLANE line_10: SO THAT DESORPTION WILL CAUSE BEST FOCUS TO DRIFT line_11: THROUGH THE NOMINAL FOCAL PLANE WITH TIME. ! !end of general form text general_form_address: lname: BRADY fname: W. mi: L. category: PI inst: PERKIN-ELMER addr_1: 100 addr_2: WOOSTER HEIGHTS RD. city: DANBURY state: CT zip: 06810 country: USA phone: (203) 794-5770 ! lname: WINCHELL fname: D. mi: G. category: CON inst: PERKIN-ELMER addr_1: 100 WOOSTER HEIGHTS RD. city: DANBURY state: CT zip: 06810 country: USA phone: (203) 794-5462 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC188-REF1 name_2: VANALTENA 924 descr_1: ALIGNMENT REFERENCE STAR pos_1: RA= 0H 41M 18.5907S +/- 0.1S, pos_2: DEC= +84D 56' 44.693" +/- 0.1", pos_3: PLATE-ID=ZZZZ, equinox: 1950 fluxnum_1: 1 fluxval_1: V=11.86, fluxval_2: B-V=0.54 ! targnum: 2 name_1: IOTACARINA-270 descr_1: SECOND MAGNITUDE FOCUS STAR pos_1: RA= 9H 15M 45.11S +/- 0.1S, pos_2: DEC= -59D 3' 53.7" +/- 0.1", pos_3: PLATE-ID=ZZZX equinox: 1950 fluxnum_1: 1 fluxval_1: V=2.25 ! targnum: 3 name_1: HR6636 name_2: HD162003 descr_1: FOCUS STAR NEAR NORTH ECLIPTIC POLE pos_1: RA= 17H 41M 55.758S +/- 0.1S, pos_2: DEC= +72D 8' 57.9" +/- 0.1", pos_3: PLATE-ID=ZZZW equinox: 2000 fluxnum_1: 1 fluxval_1: V=4.58, fluxval_2: B-V=0.42 ! targnum: 4 name_1: HR6850 name_2: HD168151 descr_1: ^ pos_1: RA= 18H 13M 52.953S +/- 0.1S, pos_2: DEC= +64D 23' 49.87" +/- 0.1", pos_3: PLATE-ID=ZZZV equinox: ^ fluxnum_1: 1 fluxval_1: V= 5.03, fluxval_2: B-V=0.39 ! targnum: 5 name_1: HR6945 name_2: HD170693 descr_1: ^ pos_1: RA= 18H 25M 58.683S +/- 0.1S, pos_2: DEC= +65D 33' 42.98" +/- 0.1", pos_3: PLATE-ID=ZZZU equinox: ^ fluxnum_1: 1 fluxval_1: V=4.82, fluxval_2: B-V=1.19 ! ! end of fixed targets !
