Notes.

(a)

Observed frequency assuming a vLSR of 5.83 km s−1.

(b)

Integrated line intensity (in mK km s−1).

(c)

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

(d)

Antenna temperature (in mK).

(e)

Predicted frequency.

(f)

Measured frequencies assuming a vLSR of 5.83 km s−1. The difference between the observed and predicted frequencies is ± 15 kHz.

(A)Partially blended with another feature. Fit still possible, providing reasonable results. (B)Blended with another feature. Fit uncertain. (C)Fully blended with a negative feature produced in the frequency switching folding. Fit unreliable. Frequency corresponds to the predicted value from the rotational constants of Table C.1. (B)Fully blended with a line from HCCCH2CN. Frequency corresponds to the predicted value from the rotational constants of Table C.1. (E)A narrow line is clearly visible, but it is affected by a negative feature. Frequency corresponds to the predicted value from the rotational constants of Table C.1. (F)Fully blended with a line from c-C3HD. Frequency corresponds to the predicted value. (G)The 51, 5 − 40, 4 line, which belongs to the para species, is fully blended with the 50, 5 − 41, 4 transition of the ortho species. Both lines have similar line strengths. (H)Unresolved doublet.
