Further access options are discussed below
For a list of all services and tables belonging to this service's resource, see Information on resource 'The USNO-B 1.0 Catalog'
You can access this service using:
Intervals of messenger energies reflected in this resource: 1.40871 3.35107 eV
This resource is not (directly) published. This can mean that it was deemed too unimportant, for internal use only, or is just a helper for a published service. Equally likely, however, it is under development, abandoned in development or otherwise unfinished. Exercise some caution.
Other services provided on the underlying data include:
The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
