Description:
Nearly 500 radio continuum sources near the Galactic plane at
declinations greater than -37 degrees were examined for radio
recombination line emission to see if they might be HII regions. A
total of 462 were detected, about half of these for the first time.
The data are presented in an extensive table. Among the newly
discovered nebulae are several with recombinations lines so narrow
that their electron temperature must be less than 4600 K. In one case
the line width (in several transitions) is only 11.6 km/s, requiring
electron temperatures less than about 2900 K.
