| The Pul-3 catalogue of 58483 stars in the Tycho-2 system
A catalogue of positions and proper motions of 58483 stars (Pul-3) hasbeen constructed at the Pulkovo observatory. The Pul-3 is based on theresults of measurements of photographic plates with galaxies (Deutsch'splan). All plates were taken using the Pulkovo Normal Astrograph (thefirst epoch is in the 1950s and the second epoch is in the 1970s).The Pul-3 catalogue contains stars of mainly 12 to 16.5 mag in 146fields with galaxies in the declination zone from -5o to+85o. The Tycho-2 has been used as a reference catalogue.The mean epoch of the Pul-3 is 1963.25. The internal positional accuracyof the Pul-3 catalogue at the mean epoch of observations is ±80mas. The accuracy of the proper motions is mostly within ±3mas/yr to ±12 mas/yr. Comparisons of the Pul-3 with Tycho-2 andARIHIP have been done at the mean epoch of the Pul-3. The Pul-3 externalpositional accuracy relative to Tycho-2 is ±150 mas.The catalogue is only available in electronic form at the CDS viaanonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/418/357

We publish 1879 radial velocities of stars distributed in 105 fields of4^{\circ} \times 4^{\circ}. We continue the PPO series \cite[(Fehrenbachet al. 1987;]{Feh87} \cite[Duflot et al. 1990, 1992 and 1995),]{Du90}using the Fehrenbach objective prism method.

| Absolute stellar proper motions with reference to galaxies of the M81 group
We report on the measurement of absolute proper motions of stars ofmagnitude 7 to 14.5 in a 2 deg X 2 deg field in the region of the M81group of galaxies. This work is part of the Bonn program for theextragalactic link of Hipparcos. The proper motions were determined froma collection of photographic plates covering the time interval from 1894to 1994. The absolute reference system for the proper motions isrepresented by the galaxies M81, M81, and NGC3077, for which accurateoptical reference positions were obtained by means of an imagecross-correlation technique. For the majority of stars, the internalproper motion accuracy is better than 1 mas/a. The precision of therealization of the absolute system is found to be around 1 mas/a. Intotal, our measurements yield absolute proper motions for 24 Hipparcosstars and positions, proper motions and photometry for 330 additionalstars including a number of visual binaries and high proper motionstars. Among the latter one G-type sub-dwarf is identified. The resultsare relevant as a contribution to the Hipparcos link, but also as adatabase for kinematic investigations.
