The ultimate goal of this third line_5: part of the Mission Support Calibration (MSC) procedure is to locate the line_6: aperture centers relative to the V2V3 reference frame with an uncertainty not line_7: exceeding 0.05 arcsec. It is preceded by Phase I (Deflection Coordinate line_8: Calibration) and Phase II (Coarse Alignment). line_10: Similar tests were used for SV (1524) and OV (1504). line_12: Revision history (1504): Richards 4/13/88, line_13: Slovak 5/20/88, Richards 6/29/88.

The line_4: aperture centers will be derived from ST step and dwell grids obtained using a line_5: star (V~8.2 mag.) in the CVZ and near the old open cluster NGC188. In line_6: order to be able to accurately position the desired object from the line_7: acquisition aperture to the appropriate science aperture, the centers line_8: of the various apertures relative to the V2V3 reference frame must be line_9: precisely determined. This will aid in the observations of single stars line_10: in crowded fields, individual components in close visual binaries and line_11: planetary satellites close to the parent planet. ! question: 3 section: 1 line_1: The observations will begin with the visual IDT (VIS) configured in the line_2: single aperture, acquisition mode and proceed as follows: line_4: 1) Mode II target acquisition to position the star (Near NGC 188) in the line_5: finding aperture (10 arcsec); line_6: 2) Take area scan image with star in center of aperture to verify position line_7: Also record FGS encoder readings; line_8: 3) Command the telescope to execute step and dwell maneuvers across the line_9: edge of the aperture while the detector is in SCP mode. The telescope will line_10: be commanded to do a step and dwell scan of the finding aperture with 0.25 line_11: arcsecond steps and centered on the edge of the aperture where the stellar line_12: image will disappear. Each step and dwell maneuver should begin at a line_13: radius of 4.8 arcsec from the aperture center and be 0.4 arcsec in length, line_14: sampled at 0.05 arcsec steps. At each step the flux in the image is collected line_15: and the FGS encoder positions are recorded. line_16: 4) Offset to a selected 1.0 arcsec aperture. line_17: Command the telescope to perform step and dwell line_18: maneuvers, as described in step 3 above. Each step and dwell line_19: maneuver should begin at a radius of 0.3 arcsec from the center and each line_20: axis length should again be 0.4 arcsec, sampled at 0.05 arcsec steps; ! question: 3 section: 2 line_1: 5) Repeat step (4) for two additional apertures. For IDT#3(VIS) line_2: the selected apertures are: 1.0-B/F450W, 1.0-A/F160LP, 1.0-A/F620W line_3: 6) Repeat steps (1) - (5) for UV2 using the following apertures: line_4: 1.0-A/F160LP, 1.0/F140LP, 1.0-B/F248M line_5: 7) Repeat steps (1) - (5) for POL , using the following apertures: line_6: 0.65-D/F160LP, F327M/POL0, F277M/POL135 line_7: and changing the parameters in the following steps: line_8: Step (1-2): finding aperture is 6.1 arcsec. line_9: Step (3): begin step and dwell 2.8 arcsec from center. line_10: 8) Repeat steps (1) - (5) for UV1 using the following apertures: line_11: 1.0/F140LP, 1.0-A/F240W, 1.O-B/F248M line_12: All scans are in spacecraft coordinates. ! question: 5 section: 1 line_1: In the OV version of this test, real-time target acquisition (Mode I) is line_2: necessary in order to position the target star precisely in the relevant IDT line_3: finding aperture. In this version, on board target acquistion is to be line_4: used. Special orientations are required in order to perform the spatial line_5: scans along different position angles across the selected apertures. All line_6: scans are in spacecraft coordinates. Telemetry format FN is required for line_7: FGS encoder position data. Scan parameters are in aperture (S/C) coordinates. line_9: The S/C DATA lines are provided to capture line_10: the FGS encoder data. The durations of the S/C DATA lines should equal line_11: those of the corresponding primary HSP lines. The given durations for line_12: the S/C lines are based on approximate HSP overheads and should be adjusted line_13: if needed to correspond to the actual HSP exposure durations. Fine line_14: lock is required for this test. ! question: 7 section: 1 line_1: Data reduction consists of deriving the count rates (or flux) for all the line_2: apertures on each IDT and associating these values with the appropriate step line_3: and dwell grid point coordinates. These data are displayed as an intensity line_4: versus position plot. line_6: In the data analysis, a smooth function will be analytically fit to the line_7: intensity versus position data for each set of axes or edge data. The V2V3 line_8: offsets are then determined, using algorithms which find the maximum of the line_9: first derivative of the intensity-position function or the half-intensity (50%) line_10: point. Using ground-based calibrations of the aperture positions, and the line_11: aperture edge positions as determined above, the aperture centers are located line_12: with respect to the edges. Finally, the aperture centers, with respect to the line_13: V2V3 axes, are derived by adding the offsets from coarse centers to the centers line_14: derived above and adding the resulting sum to the initial pointing coordinates. ! question: 10 section: 1 line_1: Data reduction and analysis will be carried out at STScI with CDBS. ! !end of general form text general_form_address: lname: WHITE fname: R mi: L category: PI inst: ST SCI addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 ! lname: WHITE fname: RICHARD mi: L. category: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA phone: (301) 338-4797 ! lname: WALTER fname: LISA mi: E. category: CON inst: SPACE TELESCOPE SCIENCE INSTITUTE addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA phone: (301) 338-5036 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: F14VID998 descr_1: STAR NEAR NGC188 IN CVZ pos_1: RA = 0H 37M 51.533S +/- 0.04", pos_2: DEC = +84D 57' 47.44" +/- 0.03" equinox: 1950 fluxnum_1: 1 fluxval_1: V=9.58 fluxnum_2: 2 fluxval_2: B-V=+0.5 ! ! end of fixed targets !
