Beginning of ReadMe : VIII/58 A Survey of Radio H II Regions in the Northern Sky (Lockman+ 1989) ================================================================================ A Survey of Radio H II Regions in the Northern Sky Lockman F.J. <Astrophys. J. Suppl. 71, 469 (1989)> =1989ApJS...71..469L ================================================================================ ADC_Keywords: H II regions ; Radio sources ; Radio lines; Surveys 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.
