Relative differences in ν_max between model F and various other models for a sample of 50 red giants. The average relative difference and standard deviation is given in brackets. The top and middle panel show δν_max that result from fitting the entire spectrum (i.e., global fit) while in the bottom panel the fits are restricted to the range around the power excess hump (i.e., local fit). In both cases, there are clear systematic differences between 1- and 2-component models.
