7092A VII/92A Open Cluster Data 5th Edition G Lynga Lund Observatory ??? ??? 1987 1987 Clusters, open Bibliography Combined data The fifth edition of the Lund Catalogue of Open Cluster Data gives key information for all known open star clusters in this galaxy. As far as possible only published data have been quoted; for some of the parameters, these values have been selected from other references, which are listed. The catalog includes cluster identification, position, reference, Trumpler classification, membership, angular diameter, mean distance, reddening, turn-off color, age, Fe/H, radial velocity, star types, magnitudes, color, number of observed stars, richness class, earliest spectral class, magnitude brightest member, galactocentric distance, linear diameter, and comments. Further errors have been corrected at CDS: see below the "Historical Notes" section. A few questions still remain (see section "Problems" below)
