Model spectral energy distribution (SED) of the Sun computed using MULTI3D@DISPATCH and the solar M3DIS snapshot. Left and right panels show the SEDs computed with the old and our new updated background bound-free opacities. The occupation probability formalism (Dappen et al. 1987) is used in the updated opacities for H I bound-free transitions. The black line shows the result of running H lines in LTE on top of the LTE background bound-free opacities. The blue line shows the model flux when tabulated LTE opacities of bound-bound radiative transitions are included.
