Notes. (a) Fluxes from Sanz-Forcada & Micela (2002). (b) STIS fluxes were corrected to match the level of the mean of the fluxes of the C III 1176 Å, Si III 1206 Å, and C II 1335 lines in the COS spectrum. (c) Summed spectrum from HSLA (Hubble Spectroscopic Legacy Archive), available at https://archive.stsci.edu/hst/spectral_legacy/. (d) Fluxes from France et al. (2010).
