Catalogue of J=1-0 CO emission towards southern dark clouds

Using the 22-m 'Mopra' antenna (near Coonabarabran, NSW) of the Australia T elescope National Facility (ATNF), we have observed emission from the 115-G Hz J = 1-0 transition of CO towards the centre of each of the 1101 clouds l isted in the Catalogue of Southern Dark Clouds (SDC) of Hartley ct al. (198 6). The velocity range covered was -96 to +70 km s(-l), with a velocity res olution of 0.120 km s(-1). CO was detected at 1049 of the positions, with 3 67 spectra showing emission at more than one radial velocity. Here we prese nt the most comprehensive general survey of the SDC catalogue, with the int ensity, velocity and half-width of the CO detection and a code describing t he profile shape. The presence of blue- or red-shifted wings in many observ ations can provide a starting point in searches for star-forming regions.
