The HII regions of M33. II. A photometric catalog of 1272 newly identified emission regions. Hodge P.W., Balsley J., Wyder T.K., Skelton B.P. <Publ. Astron. Soc. Pac. 111, 685 (1999)> =1999PASP..111..685H
ADC_Keywords: H II regions ; Photometry, H-alpha Abstract: 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 2x1034ergs/s and shows a broad maximum with a peak frequency at luminosities of 6x1035ergs/s. We also plot the H II region size distribution and comment on unusual morphologies. File Summary:

Note (1): The fluxes were measured by integrating over the area within an outer isophote level of 10-16ergs/s/cm2/arcsec2, as measured above the local background. Some of the emission regions identified in this table had no areas which were brighter than this limit and therefore no flux was measured for these objects. Note (2): The area for each object is the area on the sky within an outer isophote level of 10-16ergs/s/cm2/arcsec2^,as measured above the local background. Note (3): Unresolved emission regions are identified by the letter "u" Diffuse regions for which there is no obvious excitation source are identified by the letter "d"-------------------------------------------------------------------------------- History: From PASP electronic version
