Contour plots showing the likelihood in the T_eff-E(4405 − 5495) plane for the four stars in the second CHORIZOS run with the highest mean value for E(4405−5495). The contour intervals are linearly spaced with the minimum and maximum at 0.05 and 0.95 times the peak (mode) value, respectively. The star shows the location of the mode (not the mean) and the plots on each axis show the integrated likelihood for that parameter.
