Abstract The principle objective is to measure the location of the post-COSTAR F/48 aperture with respect to the V2V3 coordinate frame. The orientation of the detector and the reseaux axes with respect to the V2V3 axes will be used to update the PDB in the event that a significant shift in the aperture is detected. ------------------------------------------------------------------------------------ Observations Description ------------------------ Use blind pointing to acquire the selected NGC 188 astrometric field. A series of three blind pointings at the astrometric targets used in the F/96 aperture monitoring proposal will be taken to determine the location of the aperture center. This test is critical for verifying that the proper aperture location populates the PDB, something for which only astrometric observations can be used to obtain the necessary accuracy. Real Time Justification ----------------------- Calibration Justification ------------------------- The small field of view for the FOC requires highly accurate pointing in order to be assured of acquiring the target. This proposal will monitor the absolute position of the detector with respect to the FGSs in order to eliminate errors in the pointing due to the aperture location.
