Energy threshold is quite high(~ 500 GeV) if I include all the data. So as balance between including as much events as possible, I am doing my analysis with a zenith cut of 50 deg, with a threshold of about 180 GeV. ~ 70% of events and observation time of total "good" data taken.

Energy threshold is quite high(~ 500 GeV) if I include all the data. So as balance between including as much events as possible, I am doing my analysis with a zenith cut of 50 deg, with a threshold of about 180 GeV. ~ 70% of events and observation time of total "good" data taken.

Zenith < 50 deg
