Table Description:
This table is available for ADQL queries and through the TAP endpoint.
Resource Description:
For a list of all services and tables belonging to this table's resource, see Information on resource 'The USNO-B 1.0 Catalog'
This table has an associated publication. If you use data from it, it may be appropriate to reference 2003AJ....125..984M (ADS BibTeX entry for the publication) either in addition to or instead of the service reference.
To cite the table as such, we suggest the following BibTeX entry:
@MISC{vo:usnob_data, year=2008, title={The {USNO}-B 1.0 Catalog}, author={{GAVO} Data Centre}, url={http://dc.zah.uni-heidelberg.de/tableinfo/usnob.data}, howpublished={{VO} resource provided by the {GAVO} Data Center} }
This is the data table of USNO-B. Note that this data set is huge, and usually your queries will time out unless you specify a spatial region to search in.
The spurious detections listed by Barron et al (2008), http://adsabs.harvard.edu/abs/2008AJ....135..414B, have been removed, albeit with somewhat generous match radius, so 17327425 rows rather than 17224285 were deleted.
Note that the star/galaxy separation flag frequently is >11 and !=19, which should not be the case according to the documentation. We left it this way.
Surveys have been mappend onto characters, with A being the first blue survey. The survey 9 is mapped to survey 8 (i.e., H).
