Last week I updated the following routines in GSIM:
sctmed.inc, scmate.inc, geom_sc.F, init_sc.F
ectmed.inc, ecmate.inc, geom_ec.F, init_ec.F
to add pb foil in front of the TOF bars, stainless+foam backing
structure for TOF bars, and structural foam for the EC cover
plate. This was necessary to accurately simulate the energy losses
occuring in all this material, which affect the sampling fraction
of the calorimeter at low energies.
GSIM EC simulations using these changes are discussed at:
