| Abstract: | In order to compare star cluster systems in galaxies, and consequently to obtain information on their different modalities of birth and evolution, a homogeneous and complete sample of galactic open clusters is obtained from Lynga's (1983)Catalogue of Open Clusters. This sample consists of 94 open clusters whose projected (onto the galactic plane) distance from the Sun and whose absoluteV-magnitude are smaller than 2 kpc and –4.5 mag, respectively. The completeness of the sample is based only on the usual hypothesis of a uniform projected distribution of the clusters in the solar neighbourhood. Some results concerning the distribution of relevant photometric and structural parameters are presented and discussed. |
