Notes. All temperature units in this table are main-beam, Tmb. Values in parentheses are the 1σ uncertainties. The total line flux is the sum of the individual components, and the total uncertainty is calculated by adding in quadrature the individual uncertainties. We assumed a (heliocentric) systemic velocity of 1501 km s-1 (from NED) for NGC 1140, and used this as the (optical convention) reference velocity in Fig. 2.

(a)

Offsets of the component’s central velocity relative to the systemic one.

(b)

These have been corrected for beam dilution to a common beam size of 22′′ as described in Sect. 4 and Appendix A.
