abstract:

    line_1:        Aim is to determine the positions of the of the 0.4 and 0.8 arcsec f/96
    line_2:        occulting fingers and the f/48 spectrograph slit finger in the V2V3 coordinate
    line_3:        system. Once their positions are well defined, and providing they remain
    line_4:        stable with time, then Mode III target acquisition can be used to place objects
    line_5:        behind them--without the need for interactive acquisition.
    line_7:        Procedure is to do a 6x6 spatial scan with a standard astrometric star over
    line_8:        each of the fingers in turn.
    line_10:       Raster steps should be in intervals of either 0.1 (0.4 finger) or 0.2 arcsec
    line_11:       (0.8 finger) with the FOC exposing throughout the entire spatial scan.
    line_12:       Subsequent analysis should enable the extent of each finger to be determined in
    line_13:       V2V3
    line_14:       Revised 11/13/89 to match Implementation Plan

  question:        2
    section:       1
    line_1:        For the f/48 detector perform steps 1-6 using a 256x256 camera format placed
    line_2:        over the slit finger (this will require a special offset).
    line_4:        NOTES TO SCHEDULER: Real-time downlink/uplink required. Each sequence 1-7
    line_5:        (and 1-6 for f/48) will have to be repeated for both optical chains during SV
    line_6:        if the accuracies stated in the ST ScI document "Aperture Location" are to be
    line_7:        obtained. Thus, perform in F/96 phases 3 and 5, and for f/48 in 2 and 4--see

  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 selected finger,
    line_4:        using the earth through suitable solar and attenuator filters, to allow the
    line_5:        determination of the finger coordinates in SDS, i.e., detector,
    line_6:        coordinates. Downlink images for on-line analysis.
    line_8:        2. Maneuver standard astrometric star to nominal center of 512x512-F0.4 field
    line_9:        of view. Take image, downlink, determine position of the star in SDS
    line_10:       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 stability,
    line_16:       5. Carry out 6x6 spatial scan, with step = 0.1 or 0.2 arcsec and dwell =
    line_17:       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.
