Notes. (a) Rotational quantum numbers.

(b)Total angular momentum including the spin of N. When “Main” is indicated, it refers to the collapsed hyperfine components with Fu − Fi=J + l → J, J → J − l, and J − l → J − 2. In the latter case, the rest frequency corresponds to that of the strongest component.

(c)Rest frequencies used to derive the vLSR. If the uncertainty on vLSR is zero, then the frequencies correspond to those derived assuming vLSR=5.83

km s−1 (Cernicharo et al. 2020).

(d)Integrated line intensity in mKkm s−1.

(e) Velocity of the line with respect to the local standard of rest in km s−1.

(f)Line width at half-intensity using a Gaussian fit in the line profile (in km s−1).

(g) Antenna temperature (in mK). Upper limits correspond to 3σ values.

(A)The line is partially blended with an unknown feature (see Fig. 1). The line width has been fixed.

(B)Data only from the set with frequency-switching throw of 10 MHz.

(C)Blend of the hyperfine components of the same rotational transition. If the uncertainty on the velocity is zero, then the frequencies were fixed to the predicted ones and the line width was also fixed. The line parameters are correlated. The value for the total integrated intensity of the line, however, is well derived.

(D)Unresolved hyperfine structure. The frequency of the strongest component was taken as reference. Hence, the derived velocity correspond to an average of the blended hyperfine components.

(E)Data only from the set with frequency switching throw of 8 MHz.

(F)Line detected at 3σ level. The line parameters are uncertain.

(G)Blended with a negative feature produced in the folding of the frequency switching data.

(H)Blended with another feature. A fit is still possible, but the derived line parameters are uncertain.

(I)Blended with an unknown feature.

(J) Blended with CH3CN.
