More Satellites of Spiral Galaxies

We present a revised and expanded catalog of satellite galaxies of a set of isolated spiral galaxies similar in luminosity to the Milky Way. This sample of 115 satellites, 69 of which were discovered in our multiber redshift survey, is used to probe the results obtained from the original sample further (Zaritsky et al.). The satellites are, by denition, at projected separations kpc, have absolute recessional [500 velocity di erences with respect to the parent spiral of less than 500 km s~1, and are at least 2.2 mag fainter than their associated primary galaxy. A key characteristic of this survey is the strict isolation of these systems, which simplies any dynamical analysis.
