Spectrum of LALA J142442.24+353400.2, obtained with the GMOS spectrograph on Gemini North. The solid histogram shows the measured flux; the dotted line shows the one-sigma flux uncertainties. The asymmetry of the line is clearly visible.

Description
English: Spectrum of LALA J142442.24+353400.2, obtained with the GMOS spectrograph on Gemini North. The solid histogram shows the measured flux; the dotted line shows the one-sigma flux uncertainties. The asymmetry of the line is clearly visible. There is no emission at 907.2 nm, where the [OIII] 495.9 nm line would be expected if the 916 nm feature was [OIII] 500.7 nm. The spectrum was obtained using the nod & shuffle technique that allows accurate subtraction of the contaminating sky emission lines.
