SED of TYC 8252-533-1 B. The yellow, orange, and red squares indicate the photometry we measured for Gaia, SPHERE, and NACO filters, respectively. The bars in the x direction indicate the width of the filter transmission curves. The blue curve presents the median model from our posterior distribution of the SED fit as shown in Fig. D.1. We present the integrated flux of this median model in the applied filters with the grey squares and we visualize 100 randomly selected models from our posterior distribution as grey curves. In the bottom panel, we present the residuals of the fit.
