Fit of rotational splittings, for the RGB star KIC 6144777, with an échelle diagram as a function of the reduced frequency νν − (np + ε). The radial orders are indicated on the y-axis. Radial modes (highlighted in red) are centered on 0, quadrupole modes (highlighted in green), near  − 0.12 (with a radial order np − 1), and  = 3 modes, sometimes observed, (highlighted in hell blue) near 0.20. Rotational splittings are identified with the frequency of the m = 0 component given by the asymptotic relation of mixed modes, in μHz. The fit is based on peaks showing a height larger than eight times the mean background value (grey dashed lines). In order to enhance the appearance of the multiplets, highest peaks have been truncated; to enhance the short-lived radial and quadrupole modes, a smoothed spectrum is also shown, superimposed on the corresponding peaks.
