Scientific paper

This test will (1) confirm the FGS/FGS alignment to an accuracy of about 0.5 arcsec, and (2) verify the the onboard flight software control of the dominant and sub-dominant guide stars. The assumption is made that if the FGS/FGS alignment calibration is not accurate, one would see systematic offsets in the Mode III acquisition as a function of the dominant FGS and the location dominant guide star. This effect has been catalogued and trends evident in all target acquisitions performed to date. The test will determine the amount of shift and rotation of each FGS with respect to the WFPC (and therefore to each other). Using each FGS as the astrometer, a series of parallel WFPC exposures will be obtained at 3 roll angles. Any displacement of the target star in the WFPC as a function of roll indicates misalignment. The field in PRAESEPE is on the ecliptic and astrometric measurements are available (J. Russell). ***THIS PROPOSAL REQUIRES MANUAL TRANSFORMATION.**** revision 2/9/91
