Analysis A. Aguasca-Cabot lstchain v0.7.X

Overview

• Source-dependent analysis using LSTCHAIN v0.7.5 and LSTCHAIN v0.7.3 in the stage of R0 to DL1 for MC and real data.
• Cleaning method tail cut 84 and dynamic cleaning.
• Observations used in the analysis: 5580-5584, 5630-5639 and 5696-5704.
• Results presented in the LST General meeting (Nov. 2021), link here.
