Abstract
As a continuation of a project within the framework of the General Astrophysics subject (FaMAF, UNC), astrophysical parameters of 4 open clusters of the Milky Way are presented. Based on Gaia DR3 photometric data and fitting theoretical isochrones in the color-magnitude diagrams $(G_{BP}-G_{RP}, G)$, ages, metallicities, distances and color excesses $E(G_{BP}-G_{RP}, G)$ are derived for these relatively well-known open clusters. The photometric data will allow, based on color-magnitude diagrams, to analyze the aforementioned stellar aggregates in a homogeneous manner.
