Hα stick spectrum and broadened profile
==========================================

**Script:** ``examples/example_halpha.py``

Side-by-side comparison of the discrete transition stick spectrum
(``discrete_transitions``) and the static Stark-Zeeman broadened profile
at B = 0, 3, and 10 T, at two electron densities
(:math:`N_e = 10^{17}` and :math:`10^{19}` m\ :sup:`-3`), showing the
transition from the Zeeman-dominated to the Stark-dominated regime.
