Production of DL3 files for a quick-look analysis

Made by Abelardo Moralejo (IFAE) after LST-1 Analysis 2024 School

Outline of the procedure: - start from DL1 files automatically produced by the on-site analysis, LSTOSA (each night is typically ready by noon next day) - Select the relevant files for a given source, period and zenith distance range - Use already existing standard RF models to create DL2 real data files - Use the already existing MC test DL2 files (corresponding to the same “production” as the RF models) to create the IRF files - Produce the DL3 files
