Summary

Within each detector system, the time differences between the different RF signals in the event are histogrammed.
The hit # is not technically the Nth-hit in the event. Instead, it is calculated from the time.
- For example, since the RF signal arrives every 2.004 ns and is read out 1/128 times, the second hit should be ~256.5 ns later than the first, the third ~513ns after the first, etc. Thus, the hit # is determined from the delta-t. This is because sometimes a hit is missing.
- When plotting the mean of the time differences, the means are shifted in time such that they SHOULD line up at zero. E.g. if 2nd hit - 1st hit: expect to be centered at ~256.5 ns. So ~256.5ns is subtracted from the mean.
Note that sometimes there are two hits that roughly ~76ns apart from each other. They are identified as being the same hit #. The time difference between these is shown on the diagonal of the time difference distribution plots.
- This does not happen for the TOF (CAEN), only the other systems (F1TDCs).
- The means/resolutions/etc. of these hits are not shown in the characteristics summary histograms, as their values tend to dominate the other bins.
