Notes.

(a)

Rest frequency of the transition. See text for the laboratory data used for the frequency predictions of each molecular species.

(b)

Integrated line intensity in mK km s−1.

(c)

vLSR in km s−1.

(d)

Linewidth at half intensity derived by fitting a Gaussian function to the observed line profile (in km s−1).

(e)

Antenna temperature in milli Kelvin.

(1)

Quantum numbers are N, Ka, Kc, J, and F.

(2)

Quantum numbers are N and J.

(3)

The quantum number is J.

(4)

Improved rest frequencies were derived assuming a vLSR of 5.75 km s−1 (see Sect. 3.2).

(5)

Quantum numbers are J, Λ-doubling component, and F. If the hyperfine structure is not resolved in our data, then F is not given. In this case, the adopted rest frequency corresponds to the average of those of the hyperfine components.

(A)

This line is contaminated by the frequency switching negative feature of the transition 40, 4 − 30, 3 9/2-7/2 5-4 of the same species after data folding since they are separated by exactly 8.0 MHz, i.e. the frequency throw used in the observations.

(B)

This doublet appears unresolved in our data (see Fig. 1). The linewidth has been fixed to 0.6 km s−1. The resulting frequencies and intensities have slightly larger uncertainties than those of other transitions for this molecule.

(C)

The J = 3/2-1/2 F = 1-0 component is heavily blended with the J = 15-14 transition of C3S avoiding a reliable determination of the line parameters (see Fig. B.1).

(D)

The hyperfine components are only partially resolved. To obtain reliable parameters for each hyperfine component, their linewidths are fixed to 0.6 km s−1.

(E)

Heavily affected by a negative feature produced in the folding of the frequency switching data (see Fig. B.4).

(F)

This transition is heavily blended with the J = 31-30 transition of HCCN at 34566.972 MHz, which has an intensity of 2.1 mK (see Fig. B.4).
