Decomposition of the Hβ profile into absorption and narrow and broad emission Gaussian profiles. The observed spectrum and the fit to it are shown by solid lines, Gaussian profiles are shown by dashed lines, and the residual spectrum is shown by the dotted line. For a better view, the spectrum, the fit and Gaussians are shifted up by 8 × 10-17 erg s-1 cm-2 Å-1.
