TUBITAK UBV Photometry: Czernik 41 & NGC 1342

By applying the UPMASK algorithm to Gaia astrometric data for the estimation of cluster membership probabilities, we have determined that 382 stars in Czernik 41 and 111 stars in NGC 1342 exhibit the highest statistical likelihood of being cluster members.

Fundamental parameters (including reddening, metallicity, distance, and age) were derived using both classical methods, where parameters are determined separately, and Markov Chain Monte Carlo methods, where parameters are estimated simultaneously. The results obtained from both approaches are in agreement, confirming the reliability of the derived parameters and demonstrating their robustness against potential degeneracies.
