Abstract

We studied three Galactic open clusters (OC) spanning a range of age of 1 Gyr in order to compare their Mass Function (MF). In all cases, we analyzed optical multi-band images to obtain the color-magnitude diagrams (CMD). Several theoretical stellar evolution models were considered to determine distance and age of the OCs and to convert the Luminosity Function (LF) into MF. Different membership criteria were used for each OC based on cluster properties and Xray data and/or photometric IR data available in literature. The adopted methods and the comparison of the Initial Mass Functions (IMF) derived for the three OCs are presented.
