Am I having all the fun ? attached is a plot of (top panel)
Neutron bar vs position on TOF
and (bottom)
Position on neutron bar vs TOF hit
from one run last night. Although the tof TDC offset subtraction may not
be "final" (and no correction for the NC) things correlate nicely.
Of course I will fix the half-integer number for the bars and correct the
definition of position on bar. Positive means downstream, and therefore
position = left vs right. Which also (may) mean that the left side of
the bar is downstream.
Note: I HAVE CHANGED THE MAIN NTUPLE.C so as to have NC in the eep ntuple.
I did no do any changes to the other parts of the ntuple.
Note also: the reconstruction from e map for the right side neutron bars
seems to have serious problems. The e map is fine though.
