Frequency spectra for models of different stellar radius and mixing length. Top panel: the y-axis of this figure is the frequency of a given mode on the x-axis. The triangular points are measurements for a model with a radius of 10R_⊙. The circular points have a radius of 50R_⊙. The point colors indicate the mixing length of the model. Bottom panel: frequency separations between adjacent modes plotted as a function of mode. The dotted lines are models with R_* = 10R_⊙ and the solid lines are with R_* = 50R_⊙. The colors of the lines show the different mixing lengths and have the same colors as the legend in the top panel. Section 4.4.1 discusses the results of this figure.
