Hydrogen line profiles for the parametric model (solid lines) with n = 3.5 (black) and n = 3.0 (blue) compared to the averaged observed hydrogen line profiles (dotted red lines). The self-consistent model (not shown) is almost identical to the n = 3.5 parametric model. While Hβ and Hγ are reproduced well with n = 3.5, Hα and Brγ need n = 3.0 for their emission to reach the observed values.
