Fundamental and Structural Parameters of the Be97 and Di06 Open Star Clusters

We have selected two poor studied open clusters with the name of Berkeley97 and Dias06 which are located in the first and second Galactic Quadrant and containing F-G spectral type stars. CCD UBV(RI)C photometric observations of the selected clusters are taken from 0.84 m f/13 Ritchey-Chretien telescope in San Pedro Martir (SPM) National Observatory is connected to Universidad Nacional Autónoma de Mexico (UNAM). The standard data reduction procedures has been applied to CCD UBV(RI)C observations by using IRAF. We have also used 2MASS JHKS photometry to determine the fundamental and structural parameters such as limit radius [Rlim], reddenings E(B-V), photometric metal and heavy element abundances ([Fe/H], Z), distance modulus (V-Mv)o, distances d(kpc), and ages A(Gyr) of these clusters. We have used PPMXL catalogue to determine the stars as a cluster member from their proper motions.
