File includes good channels ONLY, so staus == 0.

    coeff[lay][pos] = coe;
  }

entr - number of entries

r2 - integral after 6 MIPs / entr

Histogram (0.2 MIP - 12.2 MIP) -> mean,rms, from previous iteration:
gmean,sigma,chi -> results of gaussian fit at this iteration

     coe - MPV value to use
