¥The new calibration
procedure forces the mean of the time distribution of T0N and T0P to be located
at the required time.
¥The time peaks are
rather wide (1.2 ns) and the centroid of these distributions must be determined
with an accuracy of better than 100 ps.
¥The distributions
contain both primary and secondary contributions and we assume the relative
strength of these contributions is the same for all counters on one array.
