Notes. The values qb, 
, and qe measure, respectively, the coupling for the early, middle, and late stages in the clump, defined in Mosser et al. (2014); these values are defined by 25% of the stars lying on the first, middle, and late portion of the mass-dependent evolutionary track, respectively; σq measures the spread of the values; the fits were derived from high-quality spectra with Q ≥ 50.
