Dear all,

I was playing around to produce new datasets for the EMC pid stuf. Using the PndRecoKalmanTask I could get the reconstructed momentum for each track. Also, I saw that it is possible to change the particle hypothesis. As I could see the default value is set to muon.
I have changed this to electron for electron simulations to see either the results get better or not. Unfortunately I saw that changing the hypothesis leads to even worse results for electrons. The graphs are included here (p_mc = Monte Carlo momentum and p = momentum obtained from the track after Kalman ); the macro's are available in "PndTools/MVA/macro/". Am I doing something wrong or is it expected to be like this?
