I/284/out The USNO-B1.0 Catalog (Monet+ 2003)
The Whole-Sky USNO-B1.0 Catalog of 1,045,913,669 sources (1045175762 rows)
  -c=267.855061 -28.441807
Post annotation about this record

Note: The USNO-B Catalog presents positions, proper motions, magnitudes un blue, red and infrared, as well as star/galaxy estimators for 1,045,175,762 objects derived from 3,648,832,040 separate observations. The data were taken from scans of 7,435 Schmidt plates taken from various sky surveys during the last 50 years.
USNO-B1.0 catalog was created by Dave Monet and collaborators at http://www.nofs.navy.mil/data/fchpix/
Note that the star/galaxy estimators may be mixed up in dense regions.
