Summary stellar properties (effective temperature T _eff, metallicity [Fe/H], and surface gravity ﹩\mathrm{log}(g)﹩) of the merged spectral libraries. We note that these literature measurements are extremely heterogeneous, and these data are used primarily to understand the ranges of stellar properties over which our library can provide insight. Stars with known photometric variability are plotted in orange, whereas stars not known to be variable are shown in blue.
