abstract:
line_1: Verify that the best focus position of the secondary as derived
line_2: in the OCS Focus calibrations is appropriate
line_3: for the SIs. 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.

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
