    I study 30 GeV photon and pion0 energy deposit in FMS and FHC. The number of event is 2k.

    1, the photon and pion0 is shot from (0,0,0) to (100,0,850) with 30GeV energy.

    

    2, the energy deposit in FHC of one event for photon.

 

    3, the energy weighted x, y position in FHC.

 

    4,  the energy deposit of photon and pion0 in FMS.

    5,  the energy deposit of photon and pion0 in FHC.

    6,  the energy deposit of photon and pion0 in FMS+FHC.

    This may indicate the photon pass through kind of "gap" of FMS, so I test to shoot the photon in the same cell but with a small translation in x axis. The photon and pion0 is shot from (0,0,0) to (105,0,850).

     1, the position of photon in FMS and FHC.

     2, the energy deposit in FHC of one event.

   3, the energy weighted x, y position in FHC.

   4,  the energy deposit of photon and pion0 in FMS.

   5,  the energy deposit of photon and pion0 in FHC.

   6,  the energy deposit of photon and pion0 in FMS+FHC.

      It didn't show good consistency between photon and pion0, either. I try shoot photon from (0,0,0) to (130,0,850).

     1, the position of photon in FMS and FHC. 

    2, the energy deposit in FHC of one event.

    3, the energy weighted x, y position in FHC.

    4,  the energy deposit of photon and pion0 in FMS.

    5,  the energy deposit of photon and pion0 in FHC.

    6,  the energy deposit of photon and pion0 in FMS+FHC.
