Comparison of the final synthetic spectrum to the normalized visual, UVA, and the FUSE FUV spectrum of LSS 1274. Upper panels: C III and C IV lines. The continuum adjustment of the strong C III, 1176 Ã, septuplet is problematic, which may point to a line broadening issue because the model line wings are too strong but the cores are well matched. Middle panels: N III and N IV lines. Lower panels: spectral lines of O III and the P IV&P IV lines in the P@FUV panel are well reproduced, while we consider the match for the Fev in the lower left O@FUV panel line reasonable.
