Watch your binning. Each bin in the plots you sent appears to be 4--5<br>

I would start with the raw histos to do this initial paddle-to-paddle<br>
calibration rather than the _c histos (even if you do null out the<br>
coefficients).<br>

I will also admit I don't understand the other spikes at -60 and +60<br>
on the rt_c[0]-rt_c-[1] plot, never mind the multi-spike structure on<br>
the rt_c[4]-rt_c-[5] plot... The only thing that is that periodic that<br>
we might see here is the 2ns beam structure... Do you know what the<br>
real units on your x axes are?<br></blockquote><div><br>I was multiplying by 1e+9 -- however, the analyzer source code for THaScintillator says that the resolution is 0.1e-9 seconds/channel. So maybe I should multiply by that number instead of 1e+9<br>
