Values for ε in the case of a continuous (circles) and for in the limit of a discontinuous (squares) BV profile plotted as a function of the near-core rotation frequency. The γ Dor and SPB stars are indicated in red and blue, respectively. The two γ Dor stars for which Saio et al. (2021) detected a signature of coupling between a core and envelope mode are overplotted with black symbols, namely, KIC 11907454 (cross) and KIC 12066947 (plus). Linear correlation coefficients, r_c and r_d, between ω and ε, respectively , are listed for the two samples.
