Notes. The following criteria were applied: Aij ≥ 5 × 10−4 s−1, Eup ≤ 500 K, a spectral resolution dv ≤ 0.5 km s−1, an angular resolution between 0.3 and 0.7″, and a sensitivity better than 10 mJy beam−1 for a bin width of 1 km s−1. The angular resolutions are taken from the header of the fits datacubes provided on the archive. (a)The transitions at 240.08569 GHz were not listed in the results of ATOMIS but we included them as they are in the same spectral window as the line at 240.06964 GHz and have an Eup value close to the limit of 5 × 10−4 s−1.(b)For each pair of close lines, the gup parameters differ significantly despite similar Eup and Aij.
