![The observed spectrum of the SDSS object J112655.58+004047.0 (spSpec 280 51612 635) and double-Gaussian fits to the emission lines Hβ, [O iii]λ5007, Hα, [N ii]λ6584, [S ii]λ6717 and [S ii]λ6731. The solid line is the observed line profile. The long-dashed (blue) lines are the profiles of the blue and red components, respectively, and the short-dashed (red) line is the sum of the blue and red components.
