Overview

  • Source-dependent analysis using LSTCHAIN v0.8.4, cleaning method tail cut 84 and dynamic cleaning. Also, tunned NSB and PSF.
  • Observations used in the analysis: 5580-5584, 5630-5639 and 5696-5704.

Monte Carlo information

  • Link to MC files used:
    • Particle types: gamma off0.4deg, proton
    • ZD (deg): 40
    • AZ (deg): 180
    • Other information: DL1 MC files are produced with lstMCpipe v0.5.1, but using LSTCHAIN v0.8.2. Link to DL0 MC files used:
/fefs/aswg/data/mc/DL0/20200629_prod5_trans_80/{particle}/zenith_40deg/south_pointing

DL1 data

  • LSTCHAIN v0.8.4
    • Source-dependent parameters added using script `lstchain_add_source_dependent_parameters.py`.
    • Dynamic cleaning applied using srcipt `lstchain_dl1ab.py`.
