Left panel: SED of SRGt 062340 as a function of wavelength, shown with the best-fitting model including contributions from the accretion disc, white dwarf, boundary layer, and donor star. Right panel: Corner plot of the posterior distributions from the SED fit, showing the joint and marginal probability densities for the mass-accretion rate (Ṁ) and system inclination (i). The diagonal panels display the 1D marginalised Bayesian posteriors; the red dashed lines mark the median values and the red dotted lines indicate the 68% (1σ for a Gaussian distribution) credible intervals. The off-diagonal panel shows the 2D joint contours at the nominal 68%, 95%, and 99.7% (1σ, 2σ, and 3σ for a Gaussian distribution) credible intervals, illustrating the covariance between log(Ṁ) and i.
