Left: Swift/XRT spectra of the Perseus Cluster and NGC 1275, illustrating variability in the AGN. A time-averaged spectrum is shown in black. The brightest single observation is shown in red (ObsID 34765023). Right: the difference spectrum (ObsID 34765023 minus the time-averaged spectrum), fit with an absorbed Γ = 1.7 power-law over the band with sufficient signal.
