This website gives the possibility to judge the calibration situation of
the XMM-Newton and Chandra instruments by comparing joint and individual fits
and their parameters on various targets and observations.

Flux - statistical evaluation of fluxes
statistical evaluation of fluxes
Using all available observations a histograms in various energy ranges are produced. The flux will be given relative to the
flux of the joint fit
Flux - output fluxes in various energy bands for all observations
output fluxes in various energy bands for all observations
**Method 1: A model is fitted to the whole energy range and then evaluated in the individual energy ranges regarding flux.
**Method 2: A power law model is fitted in each individual energy band and evaluated regarding flux.
