Hipparcos based astrometric analysis of M 3 and M 92 fields: optical identification of X-ray and radio sources, space motions of globular clusters M 3 and M 92 and a galactic orbit of the sdB star PG 1716+426
Received 27 July 1998 / Accepted 15 September 1998
We present positions and proper motions with respect to the Hipparcos system of stars in the fields of the globular clusters M 3 and M 92. The data were used for the optical identification of X-ray and radio sources, a new determination of the absolute proper and space motions of the globular clusters M 3 and M 92. Moreover, we derived an accurate proper and space motion of the sdB star PG 1716+426, located in the M 92 field.
