Stability of the detectors: Left one day. Rigth 8 hoursBelow 1hr.
Vertical Muon signals
Calibration with the Crab Nebula•Flux: 2.68x10-7 fotons/m2/s E>TeV•4 hours observation/day (+-30o) =14400 s•Area=500 m2
•Flux/day = 1 fotón/day
Measured Flux at la Sierra Negra300 Showers/min95% protones rejected, 50% photons Direction accuracy +/- 2o=16 minShowers in the field of view N~240 , sigma~155 sigma = 75 means 150 days of detection of the Crab.
