Isochrone fitting of the CMD of NGC 6284 corrected for differential reddening. Left panels show the best-fit corresponding to the DSED, BaSTI and PARSEC isochrones (top, middle and bottom panel, respectively) plotted as a red solid line, and the 1σ envelope shaded in orange. Right panels show the corner plots with the one- and two-dimensional projections of the posterior probability distributions for all the parameters as obtained from DSED, BaSTI and PARSEC isochrones (top, middle and bottom panel, respectively). The contours correspond to the 1σ, 2σ, and 3σ levels.
