Échelle diagrams for the low-luminosity RGB KIC 12008916 and the 2nd RC KIC 3744681. The literature values for the frequencies and mode identification are from C15 for the RGB star and from Kallinger (2019) for the RC. Same description as for the bottom panel of Fig. 13. Only statistically significant frequencies are shown, as indicated from the literature. No uncertainties are shown for the ℓ = 1 modes because smaller than the symbol sizes in most cases. For both stars, the folding Δν is Δν₀ estimated by FAMED.
