Notes.

(a)

Vibrational or torsional states that were taken into account to fit the population diagram.

(b)

The standard deviation of the fit is given in parentheses. As explained in Sect. 3 of Belloche et al. (2016), these uncertainties are purely statistical and should be viewed with caution. They may be underestimated.
