Notes.
Calculated at the excitation temperature assumed for the source. See Table A.1.
Jimenez-Serra et al. (2016) reported a column density of (1.8 − 6.3) × 1011 cm−2 based on a single transition.
Loison et al. (2016) reported a detection of propynal in Barnard 1 that is not seen in the ASAI observations with a column density of NT = 7.9 × 1011 cm−2. See text for details.
