Calibration review tool - {TITLE}

!!! Due to reprocessing of our database for migration to XSPEC12 some of the features will currently fail execution. We hope to be back to full functionality before end of April !!!

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.


Review Tool:

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

**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.
