Simulations of Au+Au 200 GeV run 10 min-bias events - simple QA

This is a simple QA for simulations of Au+Au 200 GeV run 10 min-bias events.
From the point of view of the goal of  the studies (Low-pT J/psi trigger performance test) the data are ok: single track distributions look reasonable, as well as BEMC and ToF histograms.

One thing which I don't really understand is a few entries in ToF tray Vs module histogram with try no. > 120 and entries in ToF Cell index histogram with cell index > 6 (two last histograms).

Update: As it was explained by Frank Geurts, Tray-IDs 121 and 122 are the two VPDs, and not real TOF trays. The associated cell index runs from 1-19, representing the 19 PMT tubes per VPD.

I checked the cell index for real ToF trays (Tray-IDs =< 120) and it runs from 1-6, while for  Tray-IDs > 120 the cell index runs from 1-19 as it was expected.
