Hβ and Hγ spin maximum and minimum spectra (black and blue, respectively) at ϕ₉₈ = 0.30, 0.65, and 1.0 (six left-most panels). Overplotted are the fitted spin-modulated components f_mod(λ) from Eq. (4) with amplitudes C_max and C_min (red). Below, the derived disk component is shown (green). The two right panels show the decomposition of the He Iλ4471 line at ϕ₉₈ = 0.0 and 0.30 and of He IIλ4686 at ϕ₉₈ = 0.30. No He II emission from the disk is seen, but S-wave emission is present at other orbital phases (see text).
