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

DDO photometry of the open cluster IC 4756
DDO photometry is presented for 13 red stars in the field of IC 4756,ten of which are classified as proper-motion cluster giants. Of theseten, one is found to be a dwarf, in agreement with the uvby photometryof Schmidt (1978). The strength of the delta CN cyanogen excessparameter for five of the giants indicates that the cluster hasessentially solar abundance.
