NGC 2254 and Kronberger 1 are located in the direction of Monoceros and Auriga constellations with a radial extent of 4 and 3 arcmin respectively. From the analysis of the two-colour diagrams the colour excess E(B-V) for NGC 2254 is estimated to be 0.53±0.05 mag while for Kronberger 1 it is 0.445±0.05 mag. The ZAMS and isochrones of solar metallicity were used to fit the main-sequence of the colour-magnitude diagrams to determine the distance and the log (age) of the clusters. The log (age) of the clusters NGC 2254 and Kronberger 1 are estimated to be 8.45 and 7.65 while they are placed at a distance of 2.57±0.5 kpc and 2.511±0.5 kpc respectively. The slope of mass function for NGC 2254 is found to be -2.45±0.3 and -2.62±0.18 for Kronberger 1, which are in fair agreement with the Salpeter value. |
