Radio Sources: General H-alpha Mapping of DDO 53
Abstract
DDO 53 has revealed a total of 18 H II regions. Positions, Hα luminosities, and sizes of these objects are tabulated. The luminosity function agrees, within its limited statistical significance, with the normal relation found for irregular galaxies. The size distribution has an exponential shape, as for other galaxies, with a size scale of 59+/-6 pc.
