Constructor & Destructor Documentation

EcalPedHists::EcalPedHists ( const edm::ParameterSet & ps )

Module which outputs a root file of ADC counts (all three gains) of user-selected channels (defaults to channel 1) for user-selected samples (defaults to samples 1,2,3) for user-selected supermodules.
