Scientific paper

We have prepared four cluster catalogs from Sloan Digital Sky Survey imaging data on over 400 sq-degrees of sky. From the 100,000 galaxy redshifts available, we construct velocity dispersions for the clusters of each catalog and to a new catalog constructed using velocity dispersion as a figure of merit. The resultant mass functions show very little difference, despite the large variation of cluster finding methods.
