Measured frequency assuming a v_LSR of 5.83 km s⁻¹ for TMC-1 (Cernicharo et al. 2020).

Observed minus calculated frequencies in kHz. The calculated frequencies are those resulting from the molecular constants obtained from a fit of an A-reduced Hamiltonian (representation I^r) to the observed frequencies. The derived rotational and distortion constants are given in Table 1. Unresolved doublets are fitted to the averaged frequency of the two transitions.

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

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

Antenna temperature (in milli Kelvin).

Partially blended with another feature. A fixed linewidth of 0.80 km s⁻¹ has been adopted.

Only data from the observations with frequency throw of 8 MHz.

Only data from the observations with frequency throw of 10 MHz.

Line too broad. Probably blended with another feature. Parameters are uncertain.

Line probably blended with another feature. Parameters can be derived but are uncertain.

Narrow line. Parameters are uncertain
