Absolute proper motions of open clusters. I. Observational data
Mean proper motions and parallaxes of 205 open clusters were determinedfrom their member stars found in the Hipparcos Catalogue. 360 clusterswere searched for possible members, excluding nearby clusters withdistances D < 200 pc. Members were selected using ground basedinformation (photometry, radial velocity, proper motion, distance fromthe cluster centre) and information provided by Hipparcos (propermotion, parallax). Altogether 630 certain and 100 possible members werefound. A comparison of the Hipparcos parallaxes with photometricdistances of open clusters shows good agreement. The Hipparcos dataconfirm or reject the membership of several Cepheids in the studiedclusters. Tables 1 and 2 are only available in electronic form at theCDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/Abstract.html

SANTIAGO 91, a right ascension catalogue of 3387 stars (equinox J2000).
The positions in right ascension of 3387 stars belonging to the Santiago67 Catalogue, observed with the Repsold Meridian Circle at Cerro Calan,National Astronomical Observatory, during the period 1989 to 1994, aregiven. The average mean square error of a position, for the wholeCatalogue, is +/-0.009 s. The mean epoch of the catalogue is 1991.84.

Studies on a Star Clusters: The Open Cluster T9
Photographic photometry in UBV, calibrated with standards determinedphotoelectrically, is performed on stars in the region of the opencluster T9. The color-magnitude and color-color diagrams are presented.The latter diagram shows that the interstellar reddening of the clusterstars is not larger than 0.2 magnitudes; thus the visual totalabsorption is around 0.6 magnitudes. The earliest spectral type is AO.The spectral data obtained of the three brightest stars have yielded adistance of 900 parsecs for the cluster. Furthermore the starcounts ofthe region have shown that the cluster has a diameter of 7'.2corresponding to a linear diameter of 1.8 pc. The total membership isfound to be 63 stars to a limiting magnitude V = 16.5.
