l1l2_evt Documentation

The l1l2_evt package contains the code required for accessing the L1L2Chunk which is used for persistant storage of the L1 and L2 trigger information inside the thumbnail. It contains different classes used to store/access the information relative to the L1/L2 trigger masks, to the various L1 trigger objects, to the L2 preprocessor information and to the objects used for building the L2 global triggers.

WARNING: The L1L2Chunk bitmasks are saved starting from bit number 0, whereas the trigger database always starts from bit number 1
