A test of the homogeneous array concept using the Hat Creek arrayDavid

In this memo, we review the three basic schemes of obtaining low spatial frequency data for millimeter array observations: (1) use of a large single dish, (2) interferometry with a multi-size array, and (3) scanning with a homogeneous array. We describe an application of the homogeneous array concept using the three antenna Hat Creek array. In an appendix, we analyze the eeects of random, uncorrelated pointing errors on the eeective interferometer primary beam shape, generalizing an analysis originally due to Rachel Padman and since lost.
