Notes. (a) C2O frequencies and spectroscopic parameters were extracted from the Jet Propulsion Laboratory database (JPL; Pickett et al. 1998). † Details of the detection are given in the reference reported in the last column. For the observations towards L1544 the rms on a 50 kHz frequency bin was computed over a range of 15 km s−1. The error in the main-beam temperature Tmb and Iint does not include the 10% calibration accuracy for the IRAM 30 m telescope. Bands with a Tmb value equal to 3σ rms are considered tentative detections, while we attribute the detected status to those bands with a Tmb ≥ 4σ rms.
