Overview

  • Source independent analysis using lstchain v0.9.4
  • Cleaning method: tailcut84 + pedestal cleaning + dynamic cleaning.
  • Observations: 20210809(Run5580-5584), 20210810(Run5630-5639), 20210812(Run 5696-5704)

Standard Cuts analysis

Event selection

Standard lstchain cuts were used: 

     "intensity": [100, Infinity],
     "width": [0, Infinity],
     "length": [0, Infinity],
     "r": [0, 1],
     "wl": [0.1, 1],
     "leakage_intensity_width_2": [0, 0.2],
     "event_type": [32, 32]

   "global_gh_cut": 0.7,
   "gh_efficiency": 0.9,
   "global_alpha_cut": 10,
   "global_theta_cut": 0.2,
   "theta_containment": 0.68,
   "allowed_tels": [1]
