Original · EN
We present here our first series in studying the astrophysical parameters of the open cluster "Ruprecht 15" using PPMXL1 database. In this context, the photometric, astrometry and statistical parameters for this cluster (limited radius, core and tidal radii, distances, membership, reddening, age, luminosity function, mass function, total mass, and the dynamical relaxation time) are determined for the first time.
