SED of TOI-756, constructed using broadband photometric data from APASS (magenta), Gaia (green), 2MASS (black), and WISE (blue). The upper limit for the WISE W4 band is indicated by a red dot. The horizontal error bars represent the passband widths of the respective filters. Below the SED, the residuals are shown, normalized to the photometric errors. The SED was modeled using the BT Settl atmospheric model (Allard et al. 2012) with T_eff = 3600 K, [M/H] = 0 dex, and log g_⋆ = 4.5 cm s⁻².
