Spectra of the Si IV region as in Fig. 15, but with both the STIS and the COS spectra smoothed by a seven-pixel running boxcar filter. The solid red line is the best-fit emission model for the COS spectrum minus the narrow emission components. The velocity scale along the top axis is for Si IVλ1393.755, relative to the host galaxy systemic redshift, z = 0.00973 (Theureau et al. 1998).
