The individual T _eff values from this work compared with values obtained by least-squares fitting to synthetic NextGen spectra from Mentuch et al. (2008; crosses) and those in the study of Casagrande et al. (2011; triangles) and Casagrande et al. (2008; stars). We also compare a sample of K- and M-type dwarfs which have angular diameter-based T _eff estimates from Boyajian et al. (2012b) with estimates using our SEDF implementation (circles). The values in Mentuch et al. (2008) are systematically higher than those estimated in this work, with the difference ~230 K above 4500 K, reducing to ~120 K below 4500 K. Those from the Casagrande et al. (2011) study are typically ~40 K higher than the values from this work.
