Internal catalog release (v3.1) 
The catalogs are made available in three formats.  The main catalogs contain full object information, with photometry given in units of flux normalized to AB zeropoint=25.  The magnitude catalogs contain AB magnitudes/uncertainties only; this format is suitable for input to HYPERZ.  And the .sav catalogs are in a proprietary IDL format.  See the README for details.
