Corner plot of the posterior distributions for stellar mass M_*, log₁₀(Age/yr), [Fe/H], distance d, and reddening E(B- V). Green contours are from the photometry-only fit; blue contours include photometry and the DESI rvspecfit measurements of T_eff and logg. Contours indicate the 68%, 95%, and 99.7% credible regions; diagonal panels show the corresponding one-dimensional marginalized posteriors. Titles show the median and 16th and 84th percentiles for the spectro-photometric fit.
