7. EPIC Calibration Meeting, Mallorca K. Dennerl, 2006 October 26 EPIC pn: Jumps in the energy scale Energy resolution somewhat improved during high background  reduced charge loss noise  reduced charge loss  increased trap saturation Energy shift occurs also for first singles  precursors ‘invisible’  precursors below lower threshold or in preceding frame(s) low background high background

11. EPIC Calibration Meeting, Mallorca K. Dennerl, 2006 October 26 EPIC pn: Jumps in the energy scale  During episodes of high particle background the CTI is reduced.  This is most likely caused by saturation of traps due to precursors.  The charge of the precursors is below the 20 adu threshold and thus not available.  The usual CTI correction cannot be used.  But there may be a correlation with the background flux which can be used for the correction..
