The Cygnus X Region. VI. A New 2695 MHz Continuum Survey

A 2695 MHz continuum survey of the Cygnus X region was undertaken with the NRAO 1404t telescope with an angular resolution of 11'. A reference frame was established relative to which all intensities were measured. The improved positional accuracy helped to identify the resolved sources more accurately with optical features than had been possible before. In most cases, the deviations between centers of radio and optical emission of the H ii regions are too large to be explained by positional inaccuracy. The lack of known distances of the H U regions in this area allows ouly to derive their emission measures. From a comparison between radio and H emission the visual absorption is estimated in a few cases. For IC 1318a a pair of possibly exciting stars is suggested.
