Power density spectrum of γ Psc (left) and θ¹ Tau (right). The original spectrum of the spectroscopic time series is shown in grey. The blue line shows the smoothed PDS. The red line depicts the multi-component fit to the original PDS. For γ Psc, no Gaussian profile was fitted for ν_max. The vertical black line shows the adopted value of ν_max for γ Psc and θ¹ Tau of ~32 and 90 μHz. For both stars, Fig. 1 shows the clear variations on these timescales in the time series.
