Abstract: The aim of this work was to determine physical parameters (mean distances, interstellar absorption and metallicity) of the known Open Clusters using recently published data: (a) the Gaia Data Release 2 for the identification of the members of the group, and (b) the individual stellar information given in StarHorse by combining Gaia and additional photometry. First, we verified the reliability of StarHorse determinations searching for possible systematic errors across the HR diagram. 59 well populated clusters were selected for this statistical analysis, which revealed a trend in the derivation of absorption, metallicity and distance as a function of color. Finally, we calculated the physical parameters of a set of 1340 clusters for which StarHorse provides data, and compared them with previous values in the literature
