The structure of the complex H II region IC 1318.
Abstract
The ratio of the brightnesses of the H alpha and forbidden N II lines has been measured over the IC 1318 H II complex. Several distinct maxima of this ratio were discovered. These are related to similar maxima in the brightness of the thermal radio emission from the same region.
