Table of Calibration
Energy
- Relative energy(every 144 towers) ? 2% (after ɞ% correction)
- Absolute energy ? ?2% (cosmic/hadron mip and pi0)
- Time dependence ? Studying by laser monitoring data
TOF
- Width ? 1.4nsec (mainly tower-by-tower calibration)
Yield of photon
- Geometrical acceptance ? -0.376< ? ɘ.376
-0.636< ? <-0.213 (W1) -0.190< ? ɘ.190 (W0)
- Quality assurance check ? 1.9% disabled
- TOF PID photon efficiency/background contamination ? efficiency> ? 100%, Background 50-0%
(Still large uncertainty in background contamination)
- Overlapping effect ? Studying
