We have used the Estec/Utrecht heterodyne submillimetre receiver together with the 1.4 m ESO CAT at La Silla (Chile) to survey the southern Galaxy (1 = 270 − 355°) in the CO(2–1) transition at 230 GHz (1.3 mm). The beam used had a HPBW size of 5.5 arcmin, overall system efficiency was 0.35, and the system temperature was 1400 – 1750 K (DSB). Our filterbanks had velocity resolutions of 1.3 and 0.325 km s−1 and velocity ranges of 333 and 83 km s−1 respectively.
