In each row, 3.0–80.0 keV fitted power density spectrum in the frequency range of 0.1–10.0 Hz along with its residual (first column), time-lag spectra at the corresponding fundamental QPO frequencies (second column) and fractional rms spectra at the same QPO frequencies (third column) are shown. PDS, time-lag, and rms spectra are calculated at ∼2.55 Hz (top rows), ∼4.53 Hz (middle rows), and ∼6.55 Hz (bottom rows) respectively. In all lag spectra, the 3.0–4.0 keV band is considered to be the reference band.
