Data Set Overview
  =================
  Version 2.0 of this data set includes Data Release 3 of the Sloan Digital
  Sky Survey (SDSS), including astrometric and photometric data for 204,305
  moving objects from 301 observing runs through June 2004.  The catalog
  includes various identification parameters, SDSS astrometric measurements
  (five SDSS magnitudes and their errors), and orbital elements for
  previously cataloged asteroids.
 
  An ancillary table lists the observing runs from which data are included
  in this data release, along with the dates of observation and information
  about the the sky coverage of each run.  A file containing the Sloan
  filter response curves is also included.

Confidence Level Overview
  =========================
    Note that due to problems in the 2nd data release of the SDSS MOC, it
    was never archived in PDS.  Version 1.0 of this data set comprised the
    first data release, and version 2.0 (this version) comprises the third
    data release.  Each release is cumulative and supersedes earlier
    releases.
