Notes.

^(a)

Observed frequencies for a v_LSR of 5.83 km s⁻¹. The uncertainty is 10 kHz for all lines, except for J=19-18 for which it is 20 kHz.

^(b)

Observed minus calculated frequencies in kHz.

^(c)

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

^(d)

Integrated line intensity in mK kms⁻¹
