The HII regions of M33. II. A photometric catalog of 1272 newly identified emission regions.

HODGE P.W., BALSLEY J., WYDER T.K. and SKELTON B.P.

Abstract (from CDS):

We have identified a total of 1272 newly recognized emission regions in M33. Combined with the previously cataloged total of 1066 H II regions and supernova remnants, this brings M33's total to 2338 emission regions. This paper provides photometry of the new objects in Hα, which is combined with data from previous catalogs to produce a global H II region luminosity function (corrected for incompleteness) that reaches a faint luminosity limit of 2x1034 ergs.s–1 and shows a broad maximum with a peak frequency at luminosities of 6x1035 ergs.s–1. We also plot the H II region size distribution and comment on unusual morphologies.
