Context : Aims : Astrophysical parameters ( age , reddening , distance , core and cluster radii ) of 14 open clusters ( OCs ) projected close to the Galactic plane are derived with 2MASS photometry . The OCs are Be 63 , Be 84 , Cz 6 , Cz 7 , Cz 12 , Ru 141 , Ru 144 , Ru 172 , FSR 101 , FSR 1430 , FSR 1471 , FSR 162 , FSR 178 and FSR 198 . The OCs Be 63 , Be 84 , Ru 141 , Ru 144 , and Ru 172 are studied in more detail than in previous works , while the others have astrophysical parameters derived for the first time . Methods : We analyse the colour-magnitude diagrams ( CMDs ) and stellar radial density profiles ( RDPs ) built after field-star decontamination and colour-magnitude filtered photometry . Field-star decontamination is applied to uncover the cluster ’ s intrinsic CMD morphology , and colour-magnitude filters are used to isolate stars with a high probability of being cluster members in view of structural analyses . Results : The open clusters of the sample are located at d _ { \odot } = 1.6 - 7.1 kpc from the Sun and at Galactocentric distances 5.5 - 11.8 kpc , with age in the range 10 Myr to 1.5 Gyr and reddening E ( B - V ) in the range 0.19 - 2.56 mag . The core and cluster radii are in the range 0.27 - 1.88 pc and 2.2 - 11.27 pc , respectively . Cz 6 and FSR 198 are the youngest OCs of this sample , with a population of pre-main sequence ( PMS ) stars , while FSR 178 is the oldest cluster . Conclusions :
