PPMXL photometric analysis of three open cluster candidates

We present here the astrophysical parameters of three stellar open cluster candidates using PPMXL () database. In this study, the main photometric, astrometry and statistical parameters of Ruprecht 13, Ruprecht 16 and Ruprecht 24 are estimated for the first time.
