Similar to Figure 1, except for the spectral region near prominent N i lines. For G241-6, the N i lines at 1199.55 Å, 1220.22 Å, and 1200.71 Å are shifted by +26 km s ⁻¹, +21 km s ⁻¹, and +26 km s ⁻¹, respectively, relative to the photospheric velocity. These N i lines likely are interstellar. For GD 40, the lines from Fe ii at 1199.67 Å, 1200.24 Å, and 1200.75 Å dominate in the model spectrum, and there is no evidence for any photospheric nitrogen.
