including their proper motions, based on scans of several sky surveys
conducted between 1950 and the late 1990ies.

This is a simple cone-search like interface to
the USNO-B table. You probably do not want to use this; for
a form interface to USNO-B, use
VizieR's USNO-B Form,
for advanced queries, our USNO-B table is exposed to our
TAP service.
