The test will check the focus for the HRS, FOS, line_4: FGS and PC. In the event that the focus does not satisfy line_5: SI requirements, a recommendation will be made for line_6: optimization of the focus which represents a compromise for line_7: all the SIs. ! ! end of abstract general_form_proposers: lname: ! ! end of general_form_proposers block general_form_text: question: 2 section: 1 line_1: The SI Focus Test will measure a point source as seen by the line_2: SIs at 5 secondary mirror positions. At each secondary mirror line_3: position, the following sequence of observations will be line_4: made: a set of FOS spectra acquired during a step and dwell over the line_5: 0.1 arcsec aperture using a grating to get wavelength coverage, line_6: a high resolution HRS focus diode map of the stellar image, line_7: a PC image and FGS astrometric transfer line_8: function measurements of the stars within the field. ! question: 3 section: 1 line_1: This test requires placement of the secondary mirror at the line_2: OTA best focus condition at the time of its execution. line_3: Therefore, it must be scheduled within 24 hours of an line_4: OCS focus calibration or adjustment. In the event that line_5: the focus does not satisfy SI requirements, a line_6: recommendation will be made for optimization of the focus line_7: which represents a compromise for all the SIs. ! question: 3 section: 2 line_1: The 'conditional special requirement' is invoked for line_2: the following situation: line_3: -Because of the long test duration, the target with the line_4: greatest visibility is required. Two targets and all exposure line_5: lines have been included for later selection. line_6: The offset positions of the secondary mirror listed in line_7: this proposal are defined in the same direction in which line_8: the secondary actuators are last driven to establish the best focus line_9: position. ! question: 3 section: 3 line_1: Test Procedure: line_2: 1. Command the secondary to the position of best focus line_3: determined from most recent OCS calibration . line_4: 2. Acquire target in FOS and obtain spectral map. line_5: 3. Acquire same target in HRS and obtain high resolution focus line_6: diode map. line_7: 4. Obtain FGS transfer functions on two field stars in two line_8: filters:583W,F605W line_9: 5. Obtain PC image (PC, ALL, F547M) 600 sec exposure line_10: 6. Repeat basic sequence for 5 secondary mirror offsets. line_11: 7. RESTORE SECONDARY MIRROR TO POSITION PRIOR TO TEST EXECUTION. ! question: 4 section: 1 line_1: Submitted as an Observatory Level Test ! question: 5 section: 1 line_1: Test Requirements: line_4: - The Secondary Mirror MUST be placed in the position for line_5: optimum focus as determined from the most recent OCS focus line_6: calibration . All secondary mirror offsets are given from optimum line_8: focus fiducial. At the end of the test, the secondary mirror must be placed line_9: back in the pre-OLT position. line_10: - A 10 minute period has been adopted for REAL-TIME update line_11: of the secondary mirror. A longer duration for this activity line_12: will seriously impact test efficiency. Stored commanding line_13: of the secondary motion, if possible, would significantly decrease line_14: test duration and preclude any problems from lost TDRSS contact. ! question: 5 section: 2 line_1: Test Requirements con't: line_2: - The FOS and HRS observations (and corresponding PC and FGS line_3: observations) are performed at the same defocus positions within line_4: a relatively short time. This procedure minimizes the number line_5: of times the secondary actuators are driven and also insures that line_6: FOS and HRS observations are made at exactly the same defocus line_7: positions and eliminates the question of the accuracy of line_8: repositioning the secondary at a later time. These considerations line_9: are felt to outweigh the inherent inefficiency of the procedure. line_10: - A contingency sequence has been scheduled to accommodate line_11: an unsuccessful sequence at a single secondary mirror position. line_12: The secondary setting will be determined in real time. ! question: 7 section: 1 line_1: Real Time Data Analysis Requirements: line_2: Not anticipated at this time. line_3: Offline Data Analysis Requirements: line_4: FOS Data - line_5: o Compute the flux at each offset, as a function of wavelength line_6: o Compute the best focus as a function of wavelength line_7: HRS Data - line_8: o Coordinate with HRS IDT to extract PSF FWHM line_9: o Compute the best focus line_10: PC Data - line_11: o Extract the PSF FWHM for each defocus position line_12: o Compute the best focus line_13: FGS Data - line_14: o Compute the S-curve slope at the origin and modulation line_15: o Deduce the sensitivity to each focus position and the OCS best line_16: focus position line_17: Adopted SI focus position offset: line_18: o Coordinate data analysis results with FOS and HRS IDTs ! !end of general form text general_form_address: lname: HASAN fname: HASHIMA category: PI inst: ST SCI addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA ! lname: HASAN fname: HASHIMA mi: N title: DR. inst: STSCI addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA phone: 301-338-4519 from_date: 01-JAN-87 to_date: 01-JAN-95 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: GRW+70D5824 name_2: GSC4405-1633 descr_1: BRIGHT UV STANDARD pos_1: RA = 13H 38M 51.77S +/- 0.2S, pos_2: DEC = +70D 17' 08.5" +/- 1", pos_3: PLATE-ID=0001 equinox: 2000 comment_1: PRIME TARGET comment_2: GUIDE STAR COORDINATES GIVEN fluxnum_1: 1 fluxval_1: V = 12.87 +/- 0.2 ! targnum: 2 name_1: GSC4619-662 descr_1: SECONDARY TARGET IN NGC188 pos_1: RA = 00H 40M 43.3S +/- 0.2S, pos_2: DEC = +85D 10' 37.7" +/- 1" equinox: 2000 comment_1: SECONDARY TARGET comment_2: GUIDE STAR COORDINATES GIVEN fluxnum_1: 1 fluxval_1: V = 13.00 +/- 0.3 ! targnum: 3 name_1: GSC4405-1856-REF descr_1: GS ID GIVEN descr_2: TARGET IN +70D5824 FIELD pos_1: RA = 13H 38M 54.8S +/- 0.05S, pos_2: DEC = +70D 09' 33.1" +/- 1.0", pos_3: PLATE-ID=0001 equinox: 2000 comment_1: GUIDE STAR COORDINATES GIVEN fluxnum_1: 1 fluxval_1: V = 9.5 +/- 0.5 ! targnum: 4 name_1: GSC4405-1816-REF descr_1: GS ID GIVEN descr_2: TARGET IN +70D5824 FIELD pos_1: RA = 13H 40M 22.0S +/- 0.05S, pos_2: DEC = +70D 11' 0.8" +/- 1.0", pos_3: PLATE-ID=0001 equinox: 2000 comment_1: GUIDE STAR COORDINATES GIVEN fluxnum_1: 1 fluxval_1: V = 9.54 +/- 0.5 ! targnum: 5 name_1: GSC4405-1800-REF descr_1: GS ID GIVEN descr_2: TARGET IN +70D5824 FIELD pos_1: RA = 13H 41M 18.3S +/- 0.05S, pos_2: DEC = +70D 13' 37.9" +/- 1.0", pos_3: PLATE-ID=0001 equinox: 2000 comment_1: GUIDE STAR COORDINATES GIVEN fluxnum_1: 1 fluxval_1: V = 9.5 +/- 0.5 ! targnum: 6 name_1: GSC4405-1608-REF descr_1: GS ID GIVEN descr_2: TARGET IN +70D5824 FIELD pos_1: RA = 13H 41M 44.038S +/- 0.05S, pos_2: DEC = +70D 17' 43.0" +/- 1.0", pos_3: PLATE-ID=0001 equinox: 2000 comment_1: GUIDE STAR COORDINATES GIVEN fluxnum_1: 1 fluxval_1: V = 9.92+/- 0.5 ! targnum: 7 name_1: GSC4405-1496-REF descr_1: GS ID GIVEN descr_2: TARGET IN +70D5824 FIELD pos_1: RA = 13H 41M 01.8S +/- 0.05S, pos_2: DEC = +70D 20' 51.0" +/- 1.0", pos_3: PLATE-ID=0001 equinox: 2000 comment_1: GUIDE STAR COORDINATES GIVEN fluxnum_1: 1 fluxval_1: V = 9.9 +/- 0.5 ! targnum: 8 name_1: SA0121-REF descr_2: TARGET IN +NGC188-1 FIELD pos_1: RA = 0H 42M 24.3S +/- 0.05S, pos_2: DEC = +84D 46' 37.3" +/- 1.0" equinox: 1950 fluxnum_1: 1 fluxval_1: V = 9.0 +/- 0.5 ! targnum: 9 name_1: SA081-REF descr_2: TARGET IN +NGC188-1 FIELD pos_1: RA = 0H 26M 57.3S +/- 0.05S, pos_2: DEC = +84D 45' 1.7" +/- 1.0" equinox: 1950 fluxnum_1: 1 fluxval_1: V = 9.5 +/- 0.5 ! targnum: 10 name_1: GSC4619-1262-REF descr_1: GS ID GIVEN descr_2: TARGET IN +NGC188-1 FIELD pos_1: RA = 0H 42M 03.5S +/- 0.05S, pos_2: DEC = +85D 20' 49.4" +/- 1.0" equinox: 2000 comment_1: GUIDE STAR COORDINATES GIVEN fluxnum_1: 1 fluxval_1: V = 9.7 +/- 0.5 ! ! end of fixed targets !
