These are constants whose values need to be revisited
Digitization-level constants
CDC
a_scale = 1.0E6/1.3E5
FDC
a_scale = 2.4E4/1.3E5; // for cathodes, what about wires?
FCAL
a_scale = 4.0E1/2.5E5
BCAL
a_scale = 0.0001; // 100 keV/count (?)
TOF
a_scale = 0.2/5.2E5
ADC: hit->sigma_t = 4.0; // ns (what is the fADC time resolution?)
RDC: hit->sigma_t = 0.160; // ns (what is the TOF TDC time resolution?)
t0 offset for fADC?
Start Counter
a_scale = 2.0E-2/5.2E-5
ADC: hit->sigma_t = 4.0; // ns (what is the fADC time resolution?)
RDC: hit->sigma_t = 0.160; // ns (what is the TOF TDC time resolution?)
t0 offset for fADC?
Reconstruction constants
CDC/DCDCTrackHit_factory.h
w_eff=29.5e-9; gas_gain=1e5; hit->dist = hit->tdrift*55.0E-4; // Use number hardwired in simulation for now

Various constants in DFCALCluster::shower_profile()
