V/96      Catalogue of open cluster parameters from UBV-data.  (Loktin+, 1994)

Catalogue of open cluster parameters from UBV-data. Loktin A.V., Matkin N.V., Gerasimenko T.P. <Astron. Astrophys. Trans. 4, 153 (1994)> =1994A&AT....4..153L
ADC_Keywords: Clusters, open; Combined data Description: The authors constructed the homogeneous set of galactic open cluster parameters (reddenings, distances, ages and partly metallicities) using published UBV-photometry data (Loktin, Matkin, 1992). The catalogue contains data on 340 clusters. File Summary:

Note (1): Weight is defined by quality classes of both photometrical diagrams, number of stars used and number of rejected stars. These weights are arbitrary to some extent, but we state, that clusters with weight>1 may be regarded as having good quality of estimated parameters.

Note (1): the Quality codes are A to D where A - corresponds to the diagrams with the most clearly visible sequences, D - corresponds to quite unshaped distribution of points. Digit 5 after the letter denotes the intermediate cases.
