Resumen:
By using narrow-band filters to measure the H alpha flux, a catalog of H
II regions in several spiral galaxies was made, consisting of the
position and flux of the objects. For each galaxy the H alpha luminosity
function was derived. From the observed sample, two galaxies were found
to have type II luminosity functions. Some simple models were made in
order to understand the nature of the luminosity function (both type I
and type II). The goal of our work was to simulate how a change of
star-forming region, the cluster-mass distribution, or the initial mass
function (in an evolutionary environment) can change the shape of the
luminosity function.
