Converting the posterior mean extinctions to the effective temperatures derived by GES. From the left, the image shows the effective temperatures (K) derived from GES versus the unaltered posterior mean effective temperature for each point in the sample. The middle plot shows the GES effective temperature versus the mean posterior effective temperature after adjusting the posterior mean extinction values of each star using the prescription of Section 4.8. The right plot shows the transformation using the zero-point extinction value which gave the best fit between the transformed effective temperature and the GES effective temperatures. This amounts to subtracting a |$\delta A_0=0.1$| mag amount of extinction from the posterior mean effective temperature. The hue indicates the posterior mean extinction (mag) of the star.
