Abstract This proposal will perform observations through filters F486N and F120M in F/96 mode at six despace settings of the OTA secondary mirror. The settings are designed to search for the best FOC focus position. The sweep done last summer suffered from frequent losses of lock at terminator crossings and did not provide simultaneous information from the pad positions and the encircled energy, and the optimum count rates are better known now. The data will provide a link between pad focus and encircled energy focus in the visible and the uv. The sequence should be performed at each OTA setting. The exposure with F486N filter and no ND's is to expose the pads satisfactorily. The core of the PSF will be saturated. The exposure with ND's is to measure the encircled energy within 0.1". The exposure with the F120M filter is to measure the encircled energy in the UV. After the initial acquisition and realtime uplink to move the star to the center of the field, each sequence should take 2 orbits. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.
