Overview

• Source-dependent approach using lstchain v0.9.4
• Cleaning method: tailcut84 + pedestal cleaning + dynamic cleaning.

Monte Carlo information

• Zenith 40deg, Azimuth 180 deg
• NSB and PSF tuned for RS Oph observations:

   "increase_nsb": true,
   "extra_noise_in_dim_pixels": 0.6,
   "extra_bias_in_dim_pixels": 0.269,
   "transition_charge": 8,
   "extra_noise_in_bright_pixels": 0.566,
   "increase_psf": true,
   "smeared_light_fraction": 0.175
