CO emission VS H I self-absorption

Initial results are reported of a statistical comparison of CO emission and H I self-absorption in the galactic plane at large distances from the sun. The data of Baker and Burton (1979) are used for the analysis. The area of the longitude-velocity (1-V) diagram that could be examined for H I minima and that fell within the range of the CO observations was 278 deg-km/sec. Within this area, 52 Gaussians were fitted to the H I minima. The Gaussians enclosed 6 percent of the above 1-V area within the locus of half power points. Within the same area, 52 Gaussians were fitted to the CO emission enclosing 18 percent of that area. More overlaps of Gaussian centers were noted than would be expected at random. Along with 1-V plots, a table of mean cloud parameters derived from kinematic distances is included.
