Study of structural and dynamical characteristics of open clusters (OCl). I. Results of star counts in 50 OCl's.

Star counts in 50 open clusters up to B = 16^m are carried out. Limiting radii and numbers of stars for the OCls are obtained. Parameters of the King distribution for surface star densities in the clusters, relaxation times, and tidal radii of the clusters are also determined. The estimates of concentrations of molecular clouds in the neighbourhood of the clusters under consideration are obtained by means of the CO molecular emission line catalogue.
