USNO-B1 plates

This table contains the metadata for the plates that went into USNO-B 1.0 as best as we can reconstruct it (i.e., largely those that also make up the Digital Sky Survey DSS). Most of the source files were obtained from http://www.nofs.navy.mil/data/fchpix/, some additional contributions came from Dave Monet.
