Fig. A.1
Overview of the average PSDs at different spectral shapes. PSDs are calculated on a logarithmically binned grid with df/f = 0.15. Each PSD is the average of all n PSDs falling within the Γ1 ± 0.01 interval for the given Γ1 values. Black stars show PSDs in the 2.1–4.5 keV band, red triangles in the 4.5–5.7 keV band, blue circles in the 5.7–9.4 keV, and green squares in the 9.4–15 keV band. The gray line represents the PSD in the total 2.1–15 keV band.
