IRAS sources beyond the solar circle. I. CO observations.
Abstract
We have observed ^12^CO(J = 1 - 0) with the 15-m SEST and the 30-m IRAM telescope in the direction of 1302 IRAS sources with colours of star forming regions located within 10^deg^ of the galactic plane in the interval 85^deg^ < l < 280^deg^. Emission components with line profiles that are non-Gaussian (showing e.g. possible self-absorption or wings) are identified; this information may serve as a basis for selecting sources for future research. For all components we derive kinematic heliocentric and galactocentric distances, and distances, from the galactic plane. For those components which we have associated with the IRAS sources, we derive bolometric luminosities. These data will be analysed and compared with H I data in subsequent papers.
