Outline of the procedure:

1. Start from DL1 files automatically produced by the on-site analysis, LSTOSA (each night's data is typically ready by noon next day)

2. Select the relevant files for a given source, period and zenith distance range

3. Use already existing standard RF models to create DL2 real data files

4. Use the already existing MC test DL2 files (corresponding to the same "production" as the RF models) to create the IRF files

5. Produce the DL3 files
