Relative optical and infrared photometry HAT-P-32B/HAT-P-32A. The results of the tree different literature studies are plotted together with our own J, H, and K_S band measurements. The optical relative spectrum from Fig. A.3 is also shown in light gray to emphasize the good agreement between this result and the literature photometry. The best-fit PHOENIX model relative spectrum (same as in Fig. A.3) evaluated in the same band passes as the observations is plotted in red. The points obtained in the same or very similar band passes are plotted at slightly shifted abscissa values from the actual center of the respective band pass to increase clarity of the figure.
