<p>Hi GATE users,</p>
<p>Find attached file 'SpekCalc vs GATE x-ray energy spectrum' which compares the two spectrums. My problem is the  GATE characteristics spectrum is shifted to the right a bit when compared to the characteristics energy spectrum from SpekCalc. Please, I want
 to know how I can make it align with that of spekcalc. I used the energyspectrum actor definition below</p>
