Multicomponent fitting of the Hα (top) and Hβ (bottom) lines. Below the observed (blue) and modeled (orange) spectrum, the residual (gray) and all Gaussian components are shown (blue, magenta – broad components of Hα (up) and Hβ; green – narrow lines; red – forbidden [Fe X] λ6374 and [Fe VII] λ4893 lines). The thick dashed line indicates the modeled broad line; this is the sum of all broad Gaussian components.
