Once their positions line_4: are well defined, and providing they remain stable with time, line_5: then Mode III target acquisition can be used to place objects line_6: behind them--without the need for interactive acquisition. line_7: Procedure is to do a 6x6 spatial scan with a standard astro line_8: metric star over each of the fingers in turn. line_9: Raster steps should be in intervals of either 0.2 or 0.4 line_10: arcsec (0.8 finger) with the FOC exposing throughout the line_11: entire spatial scan. Subsequent analysis should enable the line_12: extent of each finger to be determined in V2V3. line_14: NOTE: This proposal requires use of 4 filters in lines 1, 3, 5, line_15: 6.5, and 8. PEP rejects due to field length limitation. line_17: REVISED 11/2/89 BY PSTANLEY TO INCORPORATE CHANGES IDENTIFIED line_18: IN OV/2 IMPLEMENTATION REVIEW OF OV/FOC 1523. ! ! end of abstract general_form_proposers: lname: PARESCE fname: F. title: DR. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The procedure is as follows: line_3: 1. Take an external flat field, with the camera scan over the line_4: selected finger, using the earth through suitable solar and line_5: attenuator filters , to allow the determination of the line_6: finger coordinates in SDS, i.e., detector, coordinates. line_7: Downlink images for on-line analysis. line_8: 2. Maneuver standard astrometric star to nominal center of line_9: 512x512-F0.4 field of view. Take image, downlink, determine line_10: position of the star in SDS coordinates. line_12: 3. Maneuver standard star to start position of spatial scan, line_14: 4. Take an internal LED exposure--as a check on geometric line_15: stability. line_16: 5. Carry out 6x6 spatial scan, with step = 0.2 or 0.4 arcsec line_17: and dwell = 50sec, FOC exposing for entire scan. line_19: 6. Complete sequence with a second internal LED exposure. line_21: 7. Repeat steps 2-6 for 512x512-F0.8 field of view. ! question: 3 section: 2 line_1: For the f/48 detector perform steps 1-6 using a 512x512 camera line_2: format placed over the slit finger (this will require a special line_3: offset). From the analysis of this first scan we derive line_4: approximate V2V3 coordinates of the center of the slit. line_5: During the second visit the scan is performed on the slit with a line_6: fine grid, in two different locations. During the third visit, line_7: we repeat the two scans across the slit with a finer grid. line_8: COMMENTS FROM SPATIAL SCAN FORMS: line_9: SCAN FRAME IN DETECTOR COORDINATES -- SCANS DEFINED IN DETECTOR line_10: COORDINATES ACCORDING TO DOXSEY'S MEMO OF 2/25/86. ! question: 5 section: 0 line_1: line_2: NOTES TO SCHEDULER: Real-time downlink/uplink required. The line_3: sequence 1-7 will have to be repeated three times line_4: during SV if the line_5: accuracies stated in the ST ScI document "Aperture Location" line_6: are to be obtained. The observations for f/48 consist of line_7: one scan across the finger and two across the slit line_8: spaced by 60 days. line_9: These observations must be performed with HST in fine lock. line_10: PREREQUISITES: OV aperture alignment completed. ! !end of general form text general_form_address: lname: PARESCE fname: FRANCESCO category: PI ! ! end of general_form_address records fixed_targets: targnum: 3 name_1: NGC188-12 name_2: GSC4619-2511 descr_1: ASTROMETRIC STD. pos_1: RA=0H 42M 31.022S +/- 0.01S, pos_2: DEC=+85D 25' 11.67" +/- 0.1", pos_3: PLATE-ID=ZZZZ equinox: 2000 fluxnum_1: 1 fluxval_1: V=14.37 fluxnum_2: 2 fluxval_2: B-V=0.48 ! ! end of fixed targets !
