Notes. (a) Quantum numbers are N (rotational quantum number) and J (total angular momentum, J = N, N+1, N-1). They are written as NJ. (b)Calculated frequency from the laboratory data of McCarthy et al. (2000). The adopted source velocity is of -26.5 kms−1 (Cernicharo et al. 2000). (c)Energy of the upper level in K. (d)Line strength. (e)Integrated line intensity in mK kms−1. Adopted uncertainty is 10%. (f)Antenna temperature at line center in mK. (g) Antenna temperature at line horn in mK. (h)Measured data noise (1σ) in mK. (A) Heavily blended. Line parameters can not be derived. (B)Probably blended with a unidentified line.
