SED of κ And b and the blackbody fitting results. The red circles correspond to observed photometry and calculated photometry from spectra observations (synthetic photometry). The colored lines correspond to the black body fit with temperatures from 1200 K to 2400 K (fixed) and the respective best-fit radius. The color gradient corresponds to the goodness-of-fit. The dashed black line corresponds to the best-fit model (temperature and radius as free parameters).
