Data, model and residuals from fitting the PSD model to 0.3–0.7 keV (blue) and 0.7–1.5 keV (red) PSD data with (H/R)²α fixed at 0.005 and γ fixed at 0 as obtained by the global fits. The PSD displayed here are Poisson noise-subtracted and normalized in terms of squared fractional rms (Miyamoto et al. 1991). Data points consistent with zero (or negative) power have been excluded. The best-fit model parameters for each observation are listed in Table 2.
