	<i>Thresholds Scan<br />185 M3R4 chambers passed the tests</i></font> Thresholds Scan 185 M3R4 chambers passed the tests

Tables below present:
- Thr_Max(r.u.), Thresholds in register units at Maximum of noise rate;
- N_Max, Noise rate at Thr_Max in counts/sec;
- D_100 = Thr_100(r.u.) - Thr_Max(r.u.) where Thr_100(r.u.) is the threshold in register units at noise rate = 100/s.
The following expression relates the real threshold (measured from the base-line of physical signals) with the thresholds determined by the register units:
Thr(fC)*S(r.u./fC) = Thr(r.u.) - Thr_Max(r.u.)+ OFFSet(r.u.).
Here, OFFSet=17 register units;
S=3.40 r.u./fC is the charge sensitivity corresponding to S=8mV/fC taken for M3R4 chambers;
(Note, that 1 register unit = 2.35 mV)
