Notes. In the last row are shown the values of the abundance ratio of methanol to acetaldehyde for each outflow peak. (a) Region where formamide and dimethyl ether emit (Ceccarelli et al. 2017). (b) From Codella et al. (2020) based on interferometric observations. (c)Fixed rotational temperatureused to derive a range of possible Ntot. (d) Abundance ratio computed dividing the best fit column densities derived assuming that the two species are tracing the same gas with the same properties (see text).
