This is a continuation of earlier imaging studies for the MMA. Earlier work is confirmed, and the differences in imaging quality resulting from small and larger central antennas used for short-spacing information are investigated. An algorithm is presented which uses interferometer data to correct for an important component of central element pointing errors.
