I made a plot of the sum of (adc-ped)>800 for all 8 SMD crates (phi hits only...eta hits had noise problems)
I find an average delay optimum of 185.1 ns, where zero corresponds to Coarse/Fine = 104/0, implying an
optimum setting for 2013
Coarse = 104 + modulo(185.1,106.6) = 105
Fine = (185.1-106.6)/(106.6/10) = 7.3 = 7
Coarse = 105/7
