| Description | We present the HII region luminosity function and size distribution obtained for the HII regions in NGC 1365. The diameters were corrected for the effects of seeing using a Wiener image restoration procedure. The luminosities and sizes were calculated using the Cepheid distance of 18+/-2 Mpc, to NGC 1365. We find good correlation between the H_α luminosities and other properties, such as absolute magnitudes and sizes of the HII regions within this galaxy. We find that the HII region luminosity function can be fitted by a power law of slope α=-2.29±0.11, which is consistent with what is expected for its Hubble type. Also, the size distribution of the HII regions can be represented by an exponential form. |
