If not indicated otherwise (either in the text or in the captions accompanying the figures), information presented in this document comes from model simulations using the XMM Science Simulator (SciSim).
Only some figures display actual (ground-based) measurements.
Information on flux to count rate conversions comes from the HEASARC PIMMS software provided by the XMM Guest Observer Facility at NASA's Goddard Space Flight Center, based on datafiles provided by the XMM SOC, which were generated using SciSim 2.0.1.
