CCD UBV(RI)C and 2MAS S photometry of seven open clusters

© 2016 SAIt.Fundamental astrophysical parameters have been derived for Be 45, Be 55, Di 07, Feib 01, Ki 02, NGC 457 and NGC 1548 open clusters (OCs) using CCD UBV(RI)C photometric data and PPMXL database. CCD UBV(RI)C photometric data observed with the 84 cm telescope at the San Pedro Martir National Astronomical Observatory (SPMO), M exico. The cluster members and field stars in the cluster regions have separated through their Proper Motion (PM) vector point diagrams. We have used JHKs photometry of 2MAS S data taken from PPMXL catalogue to have stellar Radial Density Profile (RDP) and determine limit radius of these seven clusters. Five different Color-Magnitude diagrams ane one color-color diagram have been used together with Padova isochrones and intrinsic-colour calibrations to obtain reddenings, metallicities, distance moduli, and ages for these seven clusters
