DL1 data

Please include your settings to produce your DL1a and DL1b files. This includes whether you use LSTOSA, specific versions of lstchain, dllab scripts, cleaning levels, and calibration information.

Example :

Reprocessed using DL1a files produced by LSTOSA (lstchain v0.7.3) and dl1ab script (v0.7.5)

• original DL1a files
