Suzaku AGN observations

Spectral analysis

Broad band spectra (0.2-300 keV)

Determination continuum components

Emission line and edge structure

and then broad iron line profile

Time behaviorExcess Variance of XIS & PINExcess variance (fractional)

Therefore, PDS is given by measured excess variance.

PDS(ν1, ν2) = {σ2INT(ν2) - σ2INT(ν1)}／(ν2- ν1)

Time behaviorExcess Variance of XIS & PINThe variance is related to the power density spectrum (PDS) as

ν1

σ2INT(ν1) = ∫PDS(ν）dν
