Spectrum from the Baryon Oscillation Spectroscopic Survey (BOSS) of the newly discovered grade A candidate HAH J083420.3+452506.9 showing multiple emission lines inconsistent with the spectroscopy of the foreground early-type galaxy of 0.6495. The blue and orange lines show the observed spectrum and the best-fit SDSS model for the central lens galaxy, respectively. The vertical lines (from left to right) give the positions of the CIV-λ11549, HeII-λU640, OIII-λU664, and CIII]-λ11908 emission lines at z ≈ 1.667.
