Catalogue of Apparent Diameters and Absolute Radii of Stars (CADARS) - Third edition - Comments and statistics
The Catalogue, available at the Centre de Données Stellaires deStrasbourg, consists of 13 573 records concerning the results obtainedfrom different methods for 7778 stars, reported in the literature. Thefollowing data are listed for each star: identifications, apparentmagnitude, spectral type, apparent diameter in arcsec, absolute radiusin solar units, method of determination, reference, remarks. Commentsand statistics obtained from CADARS are given. The Catalogue isavailable in electronic form at the CDS via anonymous ftp tocdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/cgi-bin/qcar?J/A+A/367/521

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

Open clusters with Hipparcos. I. Mean astrometric parameters
New memberships, mean parallaxes and proper motions of all 9 openclusters closer than 300 pc (except the Hyades) and 9rich clusters between 300 and 500 pc have been computed using Hipparcosdata. Precisions, ranging from 0.2 to 0.5 mas for parallaxes and 0.1 to0.5 mas/yr for proper motions, are of great interest for calibratingphotometric parallaxes as well as for kinematical studies. Carefulinvestigations of possible biases have been performed and no evidence ofsignificant systematic errors on the mean cluster parallaxes has beenfound. The distances and proper motions of 32 more distant clusters,which may be used statistically, are also indicated. Based onobservations made with the ESA Hipparcos astrometry satellite

Photoelectric search for CP2-stars in open clusters. XI - NGC 3532 and NGC 5662
Delta-a photometry was carried out for 164 stars in NGC 3532 (the mostpopulous cluster studied so far in this series) and 27 stars in NGC5662. Surprisingly, only one mildly peculiar star (Koelbloed 232) wasidentified this way among the roughly hundred cluster members of NGC3532. Three photometrically peculiar objects were found among theapproximately 60 field stars in the cluster area. This is about theaverage frequency of CP2-stars, in contrast to the pronounced shortageof CP2-stars in the rather old cluster NGC 3532. In NGC 5662 twoCP2-objects, MV6 and MV10, were identified. MV6, however, is a probablenonmember based on its proper motion data. As in some previous casesagain a negative Delta-a object was found with reportedBe-characteristics (NGC 5662-MV29).

Stromgren photometry of open clusters. II - NGC3532
Stromgren photometry of B- and A-type stars in the southern open clusterNGC3532 up to V = 11.5 mag is presented. The membership of the observedstars is discussed and a reddening of E(b-y) = 0.025 for the cluster isestimated. Also, the occurrence of chemically peculiar early type (CP1and CP2) stars is examined.

UBVRI photometry in the open cluster NGC 3532
NGC 3532 is a populous open cluster of intermediate age located a fewdegrees northwest of Eta Carina. The present investigation is concernedwith observations which were conducted at the Las Campanas Observatoryin Chile during the period March-July 1981. A 61-cm telescope and UBVRIphotometer system described by Fernie (1974) were used in theobservations. The results for the cluster stars are listed in a table.Standard stars from the E regions of Cousins were used each night tocarefully determine extinctions and transformations. Attention is givento nightly rms errors for Cousins standards, the B-V color-magnitudediagram for NGC 3532, a V-R color-magnitude diagram for NGC 3532, andcomparisons of V magnitudes and B-V colors for NGC 3532
