Amplitude ratio diagram based on A_RP/A_BP and A_T/A_BP, similar to Fig. 7. The colour-coding shows the mode degree as determined with our probabilistic framework: l = 0 (green), l = 1 (blue), l = 2 (orange). The grey symbols denote stars with p<0.6. The symbol size is proportional to the probability of the mode identification. The stars marked with black outlines constitute the underlying sample from Fig. 9.
