The rotational splitting values (red filled circles for f_{j +} and blue filled triangles for f_{j −}) from the periodogram of KIC 10526294. Splittings connected to the same central (m = 0, f_j) peak are connected with a solid light grey line. Linear fits are plotted for the m = −1 peaks (dot-dashed blue line), the m = + 1 peaks (dotted red line), and the combined dataset (dashed black line).
