Observed mode splittings against the projected surface rotation rate (f_rotsin i, encircled in thin grey) or photometric surface rotation rate (f_rot, encircled in thick solid black). The three lines show the splitting values when equal to the surface rotation rate (solid) as well as one-half (dotted) and twice (dashed) the surface rotation rate. The uncertainties on the splittings indicate the maximum difference of the individual splittings to the mean splitting of the multiplet and are a measure for the asymmetry. The colours show our deterministic identifications as l = 1 (blue) and l = 2 (orange) modes.
