Spectral energy distribution (SED) of WISPIT 1 with the bestfit BT-Settle-CIFIST binary model (${\chi }_r^2=5.1$). Spectra are presented as a low resolution (high opacity) version overlaid on the high resolution (low opacity) version. The top panel displays photometric data from various sources, represented by coloured markers, alongside the combined model spectrum of the primary and secondary components. The bottom panel presents the individual model spectra for the primary and secondary star. Best-fit parameters for the primary are T_eff = 4600 K, log g = 4.0 dex, and L_bol = 0.36 L_⊙. Best-fit parameters for the secondary are T_eff = 3300 K, log g = 4.5 dex, and L_bol = 0.09 L_⊙.
