We determine structural and fundamental parameters such as cluster centre, cluster extent, reddening, age and distance of the selected region. 316 most probable members in NGC 1582 and 362 members in NGC 6604 have been identified with membership probability higher than 80%. Mean proper motions in RA and DEC are estimated as (1.99+0.084, -1.42+0.061) and (-1.55+0.036, -2.44+0.031) mas yr−1 for NGC 1582 & NGC 6604 respectively. A comparison of observed CMDs with the theoretical isochrones leads to age of these two clusters as 8.4 Myr for NGC 1582 and 6.8 Myr for NGC 6604. We found distances to be 1.1 Kpc and 1.6 Kpc for open clusters NGC 1582 & NGC 6604 respectively using parallax of member stars and isochrone fitting method. We have derived mass function slope in the cluster region. Evidence of mass segregation is also observed in both the open clusters. Keywords: Star Cluster, membership probability, mass segregation |
