An out-of-plane CO survey of the first galactic quadrant

An out-of-plane survey of 2.6-mm CO emission from the first quadrant of the galactic disk carried out at Columbia University with a 1.2-meter telescope is reported. Longitude-velocity diagrams for the galactic plane and for latitude b + or - 0.5 deg are given. The half-thickness of the CO plane, its displacement, and the emissivity of CO, all as functions of galactic radius, are shown. New results are generally consistent with those reported before.
