22. XMM-Newton Trainee Project 2004
... Data Analysis SAS News What is SAS? ... 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. ...

Cosmic ray intensities (left) compared with predictions (right) from IBEX. The similarity between these observations and predictions as evidenced by the similar color regions supports the local galactic magnetic field direction determined from IBEX observations made from particles at vastly lower energies than the cosmic ray observations shown here. The blue area represents regions of lower fluxes of cosmic rays. ...
