IRAS sources beyond the solar circle. I. CO observations Wouterloot J.G.A., Brand J. <Astron. Astrophys. Suppl. Ser. 80, 149 (1989)> =1989A&AS...80..149W
ADC_Keywords: Infrared sources; CO; Galactic plane; Radio lines; Keywords: IRAS sources - CO(1-0) emission - kinematic distances - luminosities Abstract: CO (J=1->0) has been observed with the 15-m SEST and the 30-m IRAM telescope in the direction of 1302 IRAS sources with colors of star forming regions located within 10 deg of the galactic plane in the interval between 85 and 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, kinematic heliocentric and galactocentric distances, and distances from the galactic plane are derived. For those components which may be associated with the IRAS sources, bolometric luminosities are derived. These data will be analyzed and compared with HI data in subsequent papers. File Summary:

Note (1): Due to the removal of some small bugs in our programs, and other errors, there can be a difference of ±0.01 degree in l, ±0.01kpc in R and d, ±1pc in z and ±0.1 in LIR compared to the publication. Note (2): Due to the removal of some small bugs in our programs, and other For source 1045 there are no values for T, V, dV because there is very broad emission which is not measurable with frequency switching (Remark in paper). Note (3): the symbols are: ft = flat top at = asymmetric top blue (bat) / red (rat) a = asymmetry blue (ba) / red (ra) w = wing blue (bw) / red (rw) s = shoulder blue (bs) / red (rs) cs = complex spectrum eir= emission in ref. sa = self-absorption R = remark in the publication * = observed with 30" offset in Azimuth.
