Table 3: The stellar wind energies required if the line wings are due to stellar wind-powered expanding shells and the fraction of ionizing luminosity observed, supposing the HII regions to be matter-bounded and that $R_{\rm shell}$ = 0.5 $R_{\rm reg}$ . Column 1: identification number of the HII region and the galaxy to which it belongs. Column 2: ratio of the shell kinetic energy and the stellar wind energy provided by the number of equivalent O3V stars required to provide the observed luminosity. Column 3: the stellar wind energy required to bring the energy ratio in Col. 2 to its theoretical value of 0.2. Column 4: the number of equivalent O3V stars required to provide the wind energy in Col. 3. Column 5: the logarithm of the H $\alpha$ luminosity that would be observed from an ionization-bounded HII region ionized by the number of equivalent O3V stars in Col. 4. Column 6: the percentage of the luminosity observed in each HII region.
