2 Teff broadband fitting for the subsample of heavily spotted class III sources. The extinction-corrected Asiago spectrum is shown in black, and contemporaneous photometry is shown as filled orange squares. The best-fit spectrum is shown in purple, and the corresponding T_hot and T_cool BTSettl models are reported in blue and red, respectively. Flux units are 10⁻¹³ ergs⁻¹ cm⁻² nm⁻¹.
