We present preliminary results obtained from the photometric analysis in the C and T1 bands of the Washington photometric system of four poorly studied open clusters (OCs): Dias 6, NGC 5381, Ruprecht 128 and Czernik 37, projected in the Galactic center direction. We derived their fundamental parameters from their (C − T1 , T1 ) color-magnitude diagrams, using theoretical isochrones computed for the Washington system. The present results are part of a major project which aims at characterizing almost a hundred OCs observed and analyzed in a homogeneous way.
