Notes. (a) Number of lines detected above 3σ (Table E.1). One line may mean a group of transitions of the same molecule blended together. (b) Total column density of the molecule. (c)Correction factor applied to the column density to account for the contribution of vibrationally or torsionally excited states not included in the partition function. (d) Rotational temperature (Sect. 3.2). (e)Source diameter (FWHM, Sect 3.2). (f)Velocity offset with respect to the assumed systemic velocity of the source: 74 km s−1 for Sgr B2(N3), 64 km s−1 for N4, and 60 km s−1 for N5 (Bonfand et al. 2017). (g) Linewidth (FWHM, Bonfand et al. 2017). (*)Sgr B2(N2)’s parameters are taken from Belloche et al. (2016, 2017); Müller et al. (2016) for all species, except for CH3CHO, CH3OCH3 (Belloche, priv. comm.)
