Image Details
Caption: Fig. 4.
Highest quality spectrum is shown with its fits (﹩f_{\lambda }\propto \lambda ^{\beta }﹩). This object seems to exhibit a trough consistent with being due to a bump around 220 nm (﹩\mathrm{log}\,\lambda =3.34﹩), similar to the Milky Way extinction law. The regular fit (thick line) gives ﹩\beta =-1.58\pm 0.04﹩. If we estimate β without the trough by excluding pixels in the range 1900–2500 Å, i.e., ﹩3.28\leq \mathrm{log}\,\lambda \leq 3.39﹩ (thin line), we obtain ﹩\beta =-1.26﹩ at 8 σ from the previous value. The flux is given in units of ergs s−1 cm−2 Å−1, and ﹩\mathrm{log}\,\lambda ﹩ is in units of angstroms.
