| Popis: | In this work we present JHKs near-infrared photometric study for the poorly studied open star clusters Alessi 16, Chupina1, Juchert-Saloran1 and Patchick 78 based on 2MASS data. Astrometry and photometric parameters have been calculated using the Redial Density Profile (RDP) and Color Magnitude Diagrams (CMDs) fittings. Radius, distance, reddening, age, Luminosity Function (LF), Mass Function (MF), total mass and relaxation time have been calculated from the analysis of 2MASS data. The stellar memberships have been determined using a new method. |
