!!! 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:
Additional Tools:
show all available fits
show all in the archive available fits
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.
