Caption: Figure 7.
Kiel diagram showing raw Teff and log g values. Dartmouth isochrones with ages of 12 Gyr, and [M/H] = −1.5 to 0.5 dex are overplotted. The light-gray line shows a 1 Gyr old solar-metallicity isochrone. Note that the log g discrepancy between the isochrones and ASPCAP increases below 4500 K in the main sequence.
