Line contributions to the full spectrum for model s15p2Pwr1e40 at 350 (top row), 600 (middle row), and 800 d (bottom row). In each row, we show the total normalized flux density as a black line together with the flux from individual ions (the same normalization is applied to all spectra) including H I, He I, N II, O I, O II, Na I, Mg I, Mg II, Ca II, Fe I, Fe II, and Ni II. For better visibility, we split the species into two groups and as many panels (at left and at right in each row).
