The accuracy line_15: goal of this dedicated test is 50 mas for SI/WFPC calibration. ! question: 3 section: 1 line_1: Test Description: line_4: For the SI portion of the test, each SI will acquire line_5: a nearby astrometric cluster star and (for the aperture SIs only) line_6: will center it in the target acquisition aperture using onboard line_7: TA procedures. Immediately following the acquisition and without line_8: moving the telescope, the WFPC will take an image of the line_9: cluster stars in its field of view. This pair of activities line_10: will be repeated for each SI in turn. The same pair of line_11: guides stars and roll angle will be used throughout the SI line_12: portion of the test thus eliminating systematic errors. line_13: Only small angle manuevers will adjust the vehicle for each line_14: SI sequence. ! question: 3 section: 2 line_1: For the aperture SIs (FOS,HRS, and HSP), an onboard target line_2: acquisition will be performed followed either by a peak-up line_3: (FOS) or a map. This second step is necessary since the initial line_4: acquisition does not result in the accuracy needed (as large line_5: for the FOS and HSP). The HSP peak-up procedure is not line_6: and so a MAP after the target acquisition will have line_7: have to suffice. line_8: The apertures which will be measured in this way include the line_9: following: HRS 2.0 arcsec, FOS RED and BLUE 4.3 and 0.3 arcsec, FOS BLUE line_10: 4.3 and 0.3, HSP POL 6.0 arcsec, FOC F96 512x1024 zoom (center field), line_11: (TBD FOC F48). In order to maximize scheduling efficiency, line_12: and satisfy power constraints, the order of SI sequence is line_13: specific and is TBD. ! question: 3 section: 3 line_1: The FGS portion of the test will consist of 15 min line_2: of FGS POS MODE measurements using FGS 1 and then FGS 2 as line_3: astrometers. These will be submitted in separate proposal. ! question: 4 section: 1 line_1: This is an HST alignment diagnostic test and falls under the line_2: category of Engineering/Observatory level test. ! question: 5 section: 1 line_1: SPECIAL REQUIREMENTS: THIS TEST CALLS FOR NON-STANDARD line_2: COMMANDING AND SCHEDULING: line_4: 1. GUIDING REQUIREMENT: Fine Lock for all SI Sequences. line_5: 2. GUIDE STAR SELECTION: The SAME guide star pair to be used for line_6: all SI sequences; GUIDE STAR IDS WILL BE PROVIDED VIA line_7: COLLABORATION WITH LUPIE AND SPSS EXPERTS. line_8: This is non-standard procedure. SEE BELOW. line_9: 3. All SI sequences must be performed AT THE SAME ROLL ORIENTATION line_10: in order to minimize systematic roll errors. line_11: 4. SEQUENCE NO-GAP scheduling because of stringent pointing line_12: requirements, power constraints, and to maintain a steady line_13: environment. line_14: 5. 32K Engineering - needed for analysis. line_16: 6. REPETITIONS: The test will be repeated monthly or bi-monthly. ! question: 5 section: 2 line_1: GUIDE STARS SELECTION: line_4: USE FGS 3 AS DOMINANT. USE FGS 1 AS SUBDOMINANT. This single line_5: pair MUST satisfy ALL pointings in the propoal. line_6: FOR FALL ORIENTATION ~ -91.4 DEGREES, select from the line_7: following in order of priority: line_9: FGS 3 Dominant Choice ! question: 5 section: 3 line_1: The FGS sections have been placed in a unique line_2: proposal. ! question: 6 section: 1 line_1: PLEASE READ SECTION 5. ! question: 7 section: 1 line_1: For the SI portion of the test, the data reduction will consist line_2: of the following: From the WFC images, the roll angle and line_3: absolute pointing on the sky will be calculated from the astrometic line_4: stars in it's field of view. Each SI aperture addressed in the line_5: test will be expressed in a WFC coordinate frame in arcsec. A global line_6: solution for all SIs can be made because the same guide star line_7: pair was used. Relative positions in this frame will be stored line_8: for trending. Note that the FGS/SI alignment is not addressed in this line_9: first analysis step. In the second analysis step, assumptions line_10: about the FGS/FGS alignment will have to be made in order to line_11: check the V2V3 calibration of the focal plane. line_12: REST TBD at this time. line_13: The OMS facility will be used to extract astrometry line_14: and telemetry values, existing transformation programs and line_15: spreadsheet storage will be used to store and analyze the line_16: position data. Existing image processing facilities at the line_17: STScI will be used to reduce the WFPC frames and perform line_18: plate calibrations. ! question: 8 section: 1 line_1: This is an alignment assessment test which will be line_2: repeated as needed. ! question: 9 section: 1 line_1: This is an alignment and stability assessment test which will be line_2: repeated as needed. ! question: 10 section: 1 line_1: The resources at STScI will be used in support of this line_2: observatory level procedure. ! !end of general form text general_form_address: lname: Gilmozzi fname: Roberto title: Dr. category: PI inst: STScI addr_1: 3700 San MArtin Drive city: Baltimore state: MD zip: 21218 country: USA phone: 301-338-4760 from_date: 01-JAN-88 to_date: 01-JAN-96 ! ! end of general_form_address records fixed_targets: targnum: 5 name_1: F-HRS name_2: GS1881-327 descr_2: C,202 pos_1: RA=06H 09M 9.1S +/- 0.1S, pos_2: DEC=+24D 29' 22.1" +/- 1.0" equinox: 2000 comment_1: HRS STAR IN M35 FOR comment_2: ORIENT -91.4 fluxnum_1: 1 fluxval_1: V=11.01 +/-0.3 ! targnum: 6 name_1: F-HSPPOL name_2: GS1877-1052 descr_2: C,202 pos_1: RA=06H 09M 10.78S +/- 0.1S, pos_2: DEC=+24D 21' 6.6" +/- 1.0" equinox: 2000 comment_1: HSP STAR IN M35 AT comment_2: ORIENT -91.4 fluxnum_1: 1 fluxval_1: V=13.35 +/-0.3 ! targnum: 7 name_1: F-FOC96 name_2: GS1877-494 descr_2: C,202 pos_1: RA=06H 09M 40.59S +/- 0.1S, pos_2: DEC=+24D 19' 26.3" +/- 1.0" equinox: 2000 comment_1: FOC STAR IN M35 AT comment_2: ORIENT -91.4. fluxnum_1: 1 fluxval_1: V=11.84 +/- 0.3 ! targnum: 8 name_1: F-FOSRD name_2: GS1881-222 descr_2: C,202 pos_1: RA=06H 09M 34.70S +/- 0.1S, pos_2: DEC=+24D 28' 11.7" +/- 1.0" equinox: 2000 comment_1: FOS STAR IN M35 AT comment_2: ORIENT -91.4 fluxnum_1: 1 fluxval_1: V=13.17+/-0.3 ! ! end of fixed targets !
