Abstract

In the discussion of the results of the investigation attention is given to emission nonuniformity, emission location, the electron temperature for the line-emitting region, the emission measure, the nature of the emission, small H II regions, elongated H II complexes, large and hot H I regions, small and cold clouds, and mixed emitting regions. Profile patterns indicate that the H 110-alpha recombination-line emission observed for the range from 24 deg to 33 deg originates in small-scale structures along the line of sight.
