TL;DR: X-ray observations of the core of the Perseus cluster reveal a remarkably quiescent atmosphere in which the gas has a line-of-sight velocity dispersion of 164 ± 10 kilometres per second in the region 30–60 kiloparsecs from the central nucleus, infering that a total cluster mass determined from hydrostatic equilibrium in a central region would require little correction for turbulent pressure.

TL;DR: The reproducibility of the non X-ray background model depends on the event selection criteria (such as cut-off rigidity and energy band) and the integration time, and the 1 systematic error is estimated to be less than 3% (PIN 15-40 keV) and 1% (GSO 50-100 keV), for more than 10 ks exposure.
