S. ; Dame, T. M. ; Thaddeus, P. Abstract A systematic, unbiased survey of CO emission from much of the first Galactic quadrant has been completed using the Columbia-Goddard millimeter wave telescope. The velocity resolution is 1.3 km/s and the coverage is from -13 to 153 km/s at latitude less than 55 deg and from -55 to 111 km/s at latitudes of 55 deg and higher. The noise is 0.45 K rms per 1/3 km/s resolution element. The instrument and observing technique are described and the instrument's calibration is compared with that of other telescopes. When the different beams are taken into account, the calibration agrees well with measurements of individual molecular clouds and the Galactic plane done with both the Bell Laboratories 7 m and the NRAO 11 m telescopes. The entire collection of over 3000 spectra are presented along with spatial and longitude-velocity maps.
