Descripción
We use Hα measurements of complete sets of HII regions in disc
galaxies to compute the fraction of ionizing photons which escape from
them using the hypothesis of density bounding. The escaping flux is more
than enough to ionize the observed diffuse ionized gas (DIG) and the
balance implies that an important fraction of the flux escapes into the
intergalactic medium (IGM).
