    keyword=Compton pedestal shift

    It is puzzling to see the pedestal shift in beam position and out of beam. It seems we get a baseline shift maybe still due to low energy background. First plot is run 20958 at 18.75 mm ( 3 cm out from the beam ), 2nd picture is run 20954 I guess in beam position.
