Fig. 2


Period échelle diagrams of five representative stars, two in the clump (two left-most panels) and three on the RGB, sorted by increasing Δν. The x-axis shows the period modulo of the gravity spacing ΔΠ1; the y-axis is the frequency. Diamonds indicate the observed modes, with a size proportional to the mode height. Dashed lines and crosses correspond to the asymptotic fit. Pressure and gravity orders (np, ng, respectively) and mixed-mode index nm are given for the mixed modes located near the pressure radial modes. The most p mode-like part of the pattern is located in the middle of the range, at 1/ν = ΔΠ1/2  (moduloΔΠ1).
