Hi Ian
are you sure you really did inside Mgdraw what is done in Detect?
One plot seems to be the energy *LOST* the other the energy "DEPOSITED*
which are not the same (part of the energy lost is carried by delta rays
which can escape the thin target without fully depositing its amount).
Ciao
Alfredo
