Top: Best model fit of the regions around Hβ (left) and Hα (right) of SDSS J161742.53+322234.4. The fit of the Hβ-[O III] complex includes eight Gaussian emission components: Three narrow lines (red), three broad Hβ lines (blue), and two broad [O III] lines (blue). Eight Gaussian components were also included for the Hα-[N II]-[S II] complex: Five narrow lines (red) and three broad Hα lines (blue). A first-order polynomial for the continuum is shown in green, the resulting composed model spectra in magenta, and the observed spectrum in black. Bottom: Line profiles for the Hβ (left) and the Hα (right) complexes converted into relative velocities.
