Data analyzed after the event generation. The analysis macro is written in $TER/src/event.C

88 chip analyzed and it turns out that the TP from some chip does not reach the end of the readout chain, in details:

Chip Efficiency Note
5 0 TFINE = 1008 always -> rejected in ana.C
6 3% bnknlocked between ana and event (uown)
15 0% does not see TP (known)
17 70% TD problem
70 0% does not see TP (known)
82,83,86,87 0% 8/10 bit error?

The others TP shows an efficiency above 95%. Where the efficiency is measured as:

chip_efficiency = # events with 1 TP on that chip / # total event with at least 1 TP

A TP reference for each Layer has been measured as the mode of the TP of the layer.

The time difference between this time has been measured for each TP of the Layer and it is shown that the time efficiency (TP_Chip_i = TP_Layer) is 85-95%. If we consider at least 1 clock discrepancy (TP_Chip_i = TP_Layer +- 1 clock) then the time efficiency goes above 95%

Here are saved the results of the efficiency and time efficiency of each TP: [1]
