Fig. 4.
One-dimensional observed optical spectrum in the wavelength range 7200−7650 Å of SDSS J134420.86 + 663717.8 nucleus A overlaid with the Gaussian fits. Two broad components along with three narrow components are fit to the Hα + N II complex. The black line represents the observed spectrum, the red line is the best fit, the dotted blue lines are the individual Gaussian components, and the dotted magenta line is the sum of the two broad components. The wavelength axis depicts the observed wavelength.
