The accuracy of the energy cross-calibration of the EPIC-pn camera in different operating modes was determined, using observations of the line-rich supernova remnant (SNR) Cas-A. For the Extended Full Frame (eFF) mode a special energy calibration was performed, which showed an overcorrection of the energy with respect to the Full Frame (FF) mode for the internal calibration source at aluminium and manganese energies. ...
