Summary

0000381: mcsmear BCAL: verify BCAL_mevPerPE value

Description

Elton thinks the value of BCAL_mevPerPE is off by a factor of 2:

"We looked at the code in smear_bcal.cc and find the following statement at line 398:
BCAL_mevPerPE = 1.0/( BCAL_PHOTONSPERSIDEPERMEV_INFIBER * BCAL_DEVICEPDE * BCAL_SAMPLING_FRACT );
= 1/(75x 0.21 x 0.095) = 0.67
[As an side, I think this number lacks a factor of 2 reduction in p.e. due to light guide collection, which would bring the factor up to 1.3 MeV/p.e. Is this factor missing?]"
