Percent reduction in the line-integrated flux for the SpherAcc, Polar, and MagAcc accretion geometries(top to bottom rows) from the gas opacity only. Shown are the results for the warm- (left column) and cold-population radii (right column). The dotted lines highlight an extinction A_R = 0.5, 1, 2, and 4 mag (bottom to top). At a given accretion rate, high-mass planets suffer less from absorption. For moderate Ṁ ≲ 10⁻⁵ M_J yr⁻¹, the extinction is at most A_R ≈ 0.5 mag. For SpherAcc and Polar, both radius fits yield similar results.
