Granulation intensity fluctuations A_gran as a function of the total pulsation amplitude A_puls. Symbol colours are the same as in Fig. 8. The dotted and solid line indicate unity and a power law fit, respectively. Black crosses indicate the ratio A_gran/A_puls predicted from a power law fit (shifted by –1.5 in y-direction for better visibility). Note that the fit does not include the weak dipole mode stars.
