A survey of the 12CO emission between longitudes 4° and 90° of the Galaxy is described. The survey consists of strip maps in latitude at 38 galactic longitudes, spaced at equal intervals of sin l. The maps are sampled at intervals of Δb = 2 arcmin with velocity resolutions of 0.65 and 2.6 km/s. The rms noise level of the observations is mostly better than 0.3K in the 2.6 km/s channels. The data are presented as latitude-velocity maps, as latitude-averaged profiles, and as a latitude-averaged velocity-sin l map.
