While there is practically no detector noise present at energies above , X-ray data below are considerably contaminated by noise events, which become more and more dominant towards the lowest transmitted energies (Fig. ... Investigations of 40 hours of in-orbit calibration data with the filter wheel closed, taken over a period of more than two years, showed that the noise properties vary with position and energy, but are fairly stable in time for most areas on the detector. ...
