The data is intended to explore a time-dependence or spatial dependence of the astrometry sampled at different points in the orbit to sample different breathing, velocity aberration, etc. We expect this data will allow us to push astrometry beyond the present HST calibration, benefiting current astrometry programs and opening up an enhanced capability for future programs. ------------------------------------------------------------------------------------ Observations Description ------------------------ 2 orbits of repeated scanning in the same filter, F606W, of each of the two rich star fields in program DD GO 12679 to determine the repeatability or lack thereof of high precision astrometry from spatial scanning data.
