Corner plot showing the one and two smoothed dimensional projection of the posterior probability distribution of T_eff, log(g) and [Fe/H]. The initial positions are drawn with a vertical solid blue line and a blue square respectively in the 1D and 2D projections. Vertical dashed lines in the diagonal histograms mark the 16%, 50% and 84% percentiles. The solid line contours in the 2D projections are drawn at 68% (1σ), 95% (2σ), and 99% (3σ) confidence levels.
