Solutions for NGC 2251. On the three diagonal panels we show the probability distribution functions of the variables with their medians (red solid line) and the 16th and 84th percentiles of the distribution (red dashed lines). The panels with the maps show instead the 2D-probability for each couple of parameters, highlighting possible correlations (e.g., between distance modulus and absorption). Finally, in the top-right panel we present the CMD of the cluster with the isochrone corresponding to the median parameters.
