DL1 data

Dark data :

Standard data from /fefs/aswg/data/real/DL1/ with version v0.9 and cleaning tailcut84

Moon data :

Moon data reprocessed to produce the DL1b files with the optimal cleaning for moon analysis as calculated with lstchain_dvr_pixselector -f "/fefs/aswg/data/real/DL1/2022XXXX/v0.9/tailcut84/dl1_LST-1.RunXXXXX'.*.h5" Reprocessed using DL1a files produced by LSTOSA (lstchain v0.10.XX) and dl1ab script (v0.7.5)

• original DL1a files
