Échelle diagrams of the CoRoT frequencies for HD 180642 for the large spacing determined by Belkacem et al. (2009, upper panel) and in Paper I (middle panel). For comparison, we also show the échelle diagram of the O8.5V star HD 46149 reproduced from Degroote et al. (2010b), where clear ridges produced by stochastically excited modes are found. The size of the symbols scales with the power of the frequency.
