Verification will line_4: be performed to a level of accuracy which will support the line_5: SV alignment activities. Performance will be evaluated for three line_6: continuous scan rates and extreme step/dwell scenarios. ! ! end of abstract general_form_proposers: lname: LUPIE fname: OLIVIA inst: STSCI country: USA ! lname: STOCKMAN fname: PETER inst: STSCI country: USA ! lname: BELY fname: PIERRE inst: STSCI country: USA esa: Y ! lname: NURRE fname: JERRY inst: MSFC country: USA ! ! end of general_form_proposers block general_form_text: question: 2 section: 1 line_1: To verify the performance of the Spatial Scan capability, line_2: both the WFC and PC will be used. Five spatial scan scenarios will line_3: be tested. Each scan will require two exposures, line_4: differentiated by the orthogonal directions of the scan. line_5: All CCD readouts occur after the completion of line_6: each scan. For the PC scans, the orientation of the scan will be selected line_7: to avoid the OTA diffraction spikes. line_10: A very slow scan rate will be the 3 sigma level of the expected HST pointing line_11: stability. More rapid scan rates will enable the positional accuracy line_12: to be determined as a function of the scan rate. Two step/dwell line_13: scenarios with small and large step sizes will mimic the types of line_14: spatial scans used for the SI alignnment calibrations. line_15: The use of an astrometric field will enable a coarse check on line_16: WF/PC relative CCD orientations and distortions. line_17: Estimated Test Duration: line_18: Tot t_exp = 2 hours, tot w/overhead = 4 hours. !

question: 5 section: 1 line_1: SCHEDULING REQUIREMENTS: line_3: 1) For suppression of background on longer exposures, line_4: lines #10,11,30 and 31 must be scheduled after line_5: AFTER TEC turn-on and cool down procedures line_6: (expected to occur 30 days after launch). line_7: Note: This requirement does not apply to the other scans line_8: since they are less than 300S duration. line_9: 2) This test is a critical pre-requisite to the alignments. line_10: Therefore the shorter step/dwell sequences should be scheduled line_11: in early OV. line_12: 3) The logic behind grouping each set individually comes from line_13: either different cooling requirementso or different modes. line_15: 4) No observations made during SAA passage. line_16: 5) GUIDE STAR SELECTION REQUIREMENTS: Select guide stars line_17: from GSSS special catalogue ZZZZ - Van Altena's data on NGC188. line_19: If the ZZZZ Catalog is inadequate, use the full GS catalog. ! question: 5 section: 2 line_1: line_4: Guide star acquisition must be performed before each scan to line_5: optimize guide star selection for the scan layout. line_14: TEST PREREQUISITES: line_16: - Preliminary OCS focus setting established. line_17: - Mini-OFAD verification is desireable but not necessary. line_18: - Optical image quality should be near Level 1 (lambda/8). line_19: - Test Repetition: none ! question: 5 section: 3 line_1: There are 5 unique scan sets. A scan set includes 2 orthogonal spatial line_2: scans, a fixed astrometric field image, and a K-SPOT exposure, the line_3: latter two for alignment checks. Each scan set is 'grouped' line_4: independently and with its own calibration set line_5: for scheduling requirements or scheduling flexibility. line_9: ----------------------------------------------------------- line_10: Note on Target Specification: All targets are NGC188 line_11: Van Altena stars (GSSS special catalog ZZZZ - plates 00A6 or A5). line_12: Where possible, some of the targets and therefore their line_13: associated guide stars are Van Altena Cluster members line_14: (GSSS special catalog ZZZY - cluster members subset). ! question: 7 section: 0 line_1: Real Time Data Analysis Requirements: line_3: Not anticipated at this time. line_5: Off Line Data Analysis Requirements: line_7: For the continuous raster scans: line_8: - Determine the location of each raster line (in the celestial coordinate line_9: system) and compare with the location predicted by the input to the PCS line_10: software routines. line_11: - Determine the uniformity of the slew rate by measuring the density of the line_12: asterism star trails at selected points along the scan path. line_13: - Determine the timing of the raster scan from the beginning point to the line_14: ending point and compare with the times predicted by the input to the PCS line_15: software routines. line_17: PASS Data Requirements: line_19: - FGS/SI algorithms, if modified for the use of two guide stars, will produce line_20: a string of V1 axis pointing data with both 1 second and 10 second line_21: resolution. The PASS position and timing files should be delivered at line_22: STScI within 48 hours of the downlinked observations. ! question: 9 section: 0 line_1: c. Results of this OLT will be documented in an STScI Technical Report with line_2: distribution to appropriate personnel. Portions of this test will be presented line_3: at the HST symposium following the SV mission phase. Test results may also be line_4: submitted for publication in an appropriate technical journal. ! !end of general form text general_form_address: lname: LUPIE fname: OLIVIA category: CON inst: STSCI addr_1: 3700 SAN MARTIN city: BALTIMORE state: MD zip: 21218 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: GS4619-2504 descr_1: NGC188 STAR; descr_2: GS REGION N11; descr_3: LID N188-104 pos_1: RA=0H 51M 20.83S +/-0.05S, pos_2: DEC= +85D 22' 42.20" +/-0.11", pos_3: PLATE-ID= ZZZZ equinox: 2000.0 comment_2: TARGET FOR SCAN 1; comment_3: COORDINATES FROM GSC-I comment_4: CATALOG-N188 CLUSTER. comment_5: USE FULL GS CATALOG IF ZZZZ IS comment_6: INADEQUATE. fluxnum_1: 1 fluxval_1: V=14.92 +/-0.1 fluxnum_2: 2 fluxval_2: B-V=0.62 ! targnum: 2 name_1: GS4619-1133 descr_1: NGC188 STAR; descr_2: GS REGION N2; descr_3: LID N188-255 pos_1: RA=0H 44M 21.77S +/-0.05S, pos_2: DEC= +85D 26' 30.20" +/-0.11", pos_3: PLATE-ID= ZZZZ equinox: 2000.0 comment_2: TARGET FOR SCANS 2-3; comment_3: COORDINATES FROM GSC-I comment_4: CATALOG-N188 CLUSTER. comment_5: USE FULL GS CATALOG IF ZZZZ IS comment_6: INADEQUATE. fluxnum_1: 1 fluxval_1: V=13.42 +/-0.1 fluxnum_2: 2 fluxval_2: B-V=0.19 ! targnum: 3 name_1: GS4619-1496 descr_1: NGC188 STAR; descr_2: GS REGION N2; descr_3: LID N188-14 pos_1: RA=0H 42M 43.12S +/-0.05S, pos_2: DEC= +85D 14' 14.20" +/-0.11", pos_3: PLATE-ID= ZZZZ equinox: 2000.0 comment_2: TARGET FOR SCAN 4; comment_3: COORDINATES FROM GSC-I comment_4: CATALOG-N188 STARS. comment_5: USE FULL GS CATALOG IS ZZZZ IS comment_6: AINADEQUATE. fluxnum_1: 1 fluxval_1: V=9.58 +/-0.1 fluxnum_2: 2 fluxval_2: B-V=0.50 ! targnum: 4 name_1: GS4619-273 descr_1: NGC188 STAR; descr_2: GS REGION N2; descr_3: LID N188-246 pos_1: RA=0H 41M 49.00S +/-0.05S, pos_2: DEC= +85D 05' 30.29" +/-0.11", pos_3: PLATE-ID= ZZZZ equinox: 2000.0 comment_1: WAS TARGET FOR SCAN 5 - PRESENTLY comment_2: UNUSED. comment_3: COORDINATES FROM GSC-I comment_4: CATALOG-N188 STARS. comment_5: USE FULL GS CATALOG IF ZZZZ IS comment_6: INADEQUATE. fluxnum_1: 1 fluxval_1: V=13.60 +/-0.1 fluxnum_2: 2 fluxval_2: B-V=0.64 ! targnum: 5 name_1: GS4619-973 descr_1: NGC188 FIELD; descr_2: GS REGION N2; descr_3: LID N188-81 pos_1: RA=0H 48M 59.47S +/-0.05S, pos_2: DEC= +85D 12' 29.67" +/-0.11", pos_3: PLATE-ID= ZZZZ equinox: 2000.0 comment_2: TARGET FOR PC STILL; comment_3: SELECT GUIDE STARS FROM GSC-I comment_4: CATALOG-N188 CLUSTER. comment_5: USE FULL GS CATALOG IF ZZZZ IS comment_6: INADEQUATE. fluxnum_1: 1 fluxval_1: V=13.75 +/-0.1 fluxnum_2: 2 fluxval_2: B-V=1.06 ! targnum: 6 name_1: GS4619-1986 descr_1: NGC188 STAR; descr_2: GS REGION N2 descr_3: LID N188-59; pos_1: RA=0H 47M 04.22S +/-0.05S, pos_2: DEC= +85D 15' 27.77" +/-0.11", pos_3: PLATE-ID= ZZZZ equinox: 2000.0 comment_2: TARGET FOR WFC STILL; comment_3: SELECT GUIDE STARS FROM GSC-I comment_4: CATALOG-N188 CLUSTER. comment_5: USE FULL GS CATALOG IF ZZZZ IS comment_6: INADEQUATE. fluxnum_1: 1 fluxval_1: V=14.65 +/-0.1 fluxnum_2: 2 fluxval_2: B-V=0.86 ! ! end of fixed targets !
