Times to get from target to point at which EDTM is injected

 Electron into L-HRS: (3.1 GeV/c)

  87   TOF (26 m to s2m)
  60   Signal cable from PMT
 ---
 147 ns

 Proton into R-HRS:
 
 0.585 GeV/c
 -----------
 0.53  Beta 
 151   TOF  (24 m to s2m)
  60   Signal cable from PMT
 ---
 211 ns 

 Time difference between proton and electron signals to EDTM injection point:


    0.585 GeV/c (proton)
   ------------------------------
R-L = 64 ns

The edtm configuration for this is set to (same as the previous setting)

./edtmsetup 0 112 232

though the proton comes about 23 ns earlier for this setting.


The T5 coincidence is formed with an overlap between T1 and T3.  The
electron (T3) was chosen to carry the T5 time.  To get a proper delay
with the EDTM pulses, I choose the following delay for T3:

./t3_delay 72

same as before to preserve the previous timing.
