OF ASTRONOMY ! end of coverpage abstract: line_1: Using a standard star (V 8.2 mag.) in the CVZ near the open cluster line_2: NGC188, the instantaneous locations of the centers of the acquisition line_3: aperture and various small science apertures will be determined with line_4: respect to the V2V3 reference system. 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: This test is unique to OV. A different test has been submitted for SV line_11: purposes. line_12: Note: This is RPSS file 1504. Revision history: 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 I target acquisition to position the star (Near NGC188) in the line_5: finding aperture (10 arcsec); line_7: 2) Command the DF-224 to execute four single axis step and dwell maneuvers line_8: across the edge of the aperture, each axis being 90 degrees apart. The HSP line_9: will be commanded to do a 20x20 image of the finding aperture with 0.25 line_10: arcsecond steps and centered on the edge of the aperture where the stellar line_11: image will disappear. Each step and dwell maneuver should begin at a line_12: radius of 4.8 arcsec from the aperture center and be 0.4 arcsec in length, line_13: sampled at 0.05 arcsec steps. At each step the flux in the image is collected line_14: and the FGS encoder positions are recorded. line_16: 3) Reposition star to center of finding aperture and offset to a selected 1.0 line_17: arcsec aperture. Command the DF-244 to perform four single axis step and line_18: dwell maneuvers, as described in step 2 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: 4) Relocate the star to the coarse center of the finding aperture to position line_2: the target and obtain an area scan. Also record FGS encoder readings; line_4: 5) Repeat steps (3) - (4) for one additional aperture. Then repeat steps 1, 2, line_5: 3, and 4 for a third aperture and then repeat steps 3 and 4 again for the first line_6: aperture to test repeatibility. For IDT#3(VIS) the selected apertures are: line_7: 1.0-B/F450W, 1.0-A/F160LP, 1.0-A/F620W, 1.0-B/F450W (repeat) line_9: 6) Repeat steps (1) - (5) for UV2 using the following apertures: line_10: 1.0-A/F160LP, 1.0/F140LP, 1.0-B/F248M, 1.0-A/F160LP (repeat) line_12: 7) Repeat steps (1) - (5) for POL , using the following apertures: line_13: 0.65-D/F160LP, F327M/POL0, F277M/POL135, 0.65-D/F160LP (repeat) line_14: and changing the parameters in the following steps: line_16: Step (1): finding aperture is 6.1 arcsec line_17: Step (2): begin step and dwell 2.8 arcsec from center. line_19: 8) Repeat steps (1) - (5) for UV1 using the following apertures: line_20: 1.0/F140LP, 1.0-A/F240W, 1.0-B/F248M, 1.0/F140LP (repeat) line_21: All scans are in spacecraft coordinates. ! question: 5 section: 1 line_1: Real-time target acquisition (Mode I) is necessary in order to position the line_2: target star precisely in the relevant IDT finding aperture. Special line_3: orientations are required in order to perform the spatial scans along different line_4: position angles across the selected apertures. All scans are in spacecraft line_5: coordinates. Telemetry format FN is required for FGS encoder position data. line_7: Scan parameters are in aperture (S/C) coordinates. HSP tests iA through iG, line_8: i1, 01a, 01b, and 03 must be complete before this test is begun. line_10: The S/C DATA lines are provided to capture the FGS encoder data. The durations line_11: of the S/C DATA lines should equal those of the corresponding primary HSP line_12: lines. The given durations for the S/C lines are based on approximate HSP line_13: overheads and should be adjusted if needed to correspond to the actual HSP line_14: exposure durations. Fine 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 supported at the Astronomy Department line_2: at the University of Wisconsin in Madison. ! !end of general form text general_form_address: lname: DOLAN fname: JOSEPH mi: F. title: DR. category: CON inst: GSFC addr_1: CODE 681 city: GREENBELT state: MD zip: 20771 country: USA phone: (301)286-5920 ! lname: SLOVAK fname: MARK mi: H. title: DR. category: CON inst: UNIVERSITY OF WISCONSIN addr_1: 475 N.
