Notes.

a

Observed frequency assuming a vLSR of -26.5 km s−1.

b

Observed minus calculated frequencies in MHz.

c

Integrated line intensity in mK km s−1. Uncertainty is assumed to be dominated by the calibration uncertainty of 10%. This uncertainty has been multiplied by a factor of 3 for the J = 43-42 transition due to the poor atmospheric transmision at 50.1 GHz.

d

Antenna temperature at the terminal velocity (horn) in milli Kelvin.

e

Antenna temperature at line center in milli Kelvin.

f

Root mean square noise of the data.

A

Blended with HCCCCC13CCN. Line parameters can be still fitted.

B

Blended with C3H. Line parameters can be still fitted.

C

Blended with HC7N v15. Line parameters can be still fitted.

D

Blended with CH3C3N. Line parameters can be still fitted.

E

Blended with a U feature. Line parameters very uncertain.

F

Calibration very uncertain.
