Comparisons of radii and temperatures recovered for individual stars with those predicted by the SPOTS models, as a function of f_spot. Markers are colored by their f_spot and lines are also colored by the corresponding f_spot theoretical starspot isochrones from SPOTS. Inset plots relate the observed f_spot recovered from the spectra (x-axis) to the spot filling fraction inferred from the isochrones using the measured radii (y-axis).
