| 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) | USNO-B1.0===0544-0274284 |
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.
