Radiation monitoring for FPS

First look at the radiation sensor data in June 2015, starting on day 15 (Monday evening).
The thermistor data has been translated into the temperature:
Silicon and REM data is the read-back voltage for currents of 0.025 A and 0.00016 A.
Three sensors are located at (looking at the FPS from the hall) top-left, left, bottom (at the location of the SiPM in layer 1).
The thermistor data has been translated into the temperature:
Double_t temperature( Double_t v, Double_t i) { const Double_t beta = 3530; const Double_t CtoK = 273.15; const Double_t r_ntc = 10000.0; return ( 1.0/(1.0/(25. + CtoK) + 1.0/beta*(TMath::Log((v/i)/r_ntc))) - CtoK); }
Silicon and REM data is the read-back voltage for currents of 0.025 A and 0.00016 A.
