Use of IRAS data to define H II regions
A total of 2298 IR H II regions in the IRAS Point Source Catalog are identified to a confidence level of 77 percent. A latitude-longitude plot shows that most of these regions lie in the region + or - 3 degrees of the galactic plane. A set of 949 IRAS sources are shown to be planetary nebulae to a 79 percent confidence level. These sources are found within 10 degrees of the plane. Seven of the objects studied are observed with VLA as a test of the analysis. 32 references.
