Photon-statistics factor for smearing hit energy (from Crisss MC) (copied from DFCALMCResponse_factory.cc 7/2/2009 DL) Single block energy threshold (applied after smearing) 20 MeV, units are in GeV Attenuation length in cm. effective speed of light in glass in cm/ns block width in cm block length in cm time windown for two hit separation in ns maximum number of hits in a single block threshold applied in a block (in hdgeant) Note: different unit than for smeared-blocks threshold (see above) radius of the calorimeter number of blocks in central row number of blocks in central column
