Notes.

^(a)

Observed frequencies adopting a v_LSR of 5.83 km s⁻¹ for TMC-1. The uncertainty is 10 kHz for all the lines.

^(b)

Observed minus calculated frequencies in kHz.

^(c)

Integrated line intensity in mK km s⁻¹.

^(d)

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