Cohen, R.S., and P. Thaddeus, 1977: An out-of-plane galactic carbon monoxide survey. Astrophys. J., 217, L155-L159, doi:10.1086/182560.

Galactic CO line emission at 115 GHz has been surveyed in the region 15° < l < 60° and -1.5° ~< b ~< 1.5° latitude. In addition to confirming the findings of previous in-plane surveys that galactic CO emission is concentrated in a ring 6 kpc in radius, a fit of a cylindrically symmetric galactic model to the observational data has provided a determination of the thickness of this molecular ring and its displacement from the conventional galactic plane, both as functions of galactocentric distance. The average half-thickness at half-maximum of the molecular ring is 59 pc, and the average displacement of the ring with respect to the b = ° plane is -40 pc.
