Toward the HIPPARCOS link: astrometry of stars and extragalactic sources in the field of the spiral galaxy M51.
We present absolute proper motions of 14 Hipparcos stars from groundbased photographic astrometry in a 2x2deg field around the spiral galaxyMessier 51. These are part of a catalogue of 340 stars with B<=16,for which positions, proper motions, and B magnitudes have been derivedfrom a series of 16 photographic plates. Due to large epoch differencesof up to 88 years between the observations, the proper motion accuracyis typically <=1mas/a. An extragalactic calibration of the propermotion zero-point is achieved by measuring the fictitious proper motionsof bright extragalactic objects in the field. For this purpose, across-correlation technique was developed. The resulting precision ofthe proper motion link to an extragalactic frame is estimated as1.0mas/a. Measurements of double stars and high proper motion stars arealso discussed.
