Dear FLUKA experts, I've noticed that graphs have not been attached. Please see them in the separated files.

I'm particularly interested in photons at 20 cm depth. For that I defined 0.01 cm thin volume within water cube by using XYP plane. To score energy of photons I chose tabs USRTRACK with AUXSCORE for that volume. The results I've got are fine however I wanted see if USRBDX will give me the same spectra. I specified boundaries to cover the same region as in USRTRACK (also I added AUXSCORE command to score exatly energy of photons). The results I normalized (according to manual) as follows: USRTRACK = Y(axis) * energy bin (I get rid of 'per GeV')* number of particles (I get rid of 'per primary'), so I get fluence in cm^{-2} USRBDX = Y(axis)* energy bin*2pi (because I requested one way scoring) *number of particles. The results I've got are: USRBDX 1. ENERGY -34. TARGET TARGET6 100.usrbdx_his USRBDX 0.2 0.1 200. 0.0 1. & [X] USRTRACK 1. ENERGY -30. TARGET6 100. 400.histogram6 USRTRACK 0.2 0.1 & [X] I would like to ask how can I explain difference between these two spectra? I have noticed that whenever I change the thickness of my volume fluence increases in USRTRACK. So how thick should be my scoring volume to get the same results as for USRBDX?
