Event

class BasicEventSelection : public xAH::Algorithm

This algorithm performs the very basic event selection. This should be the first algo in the algo chain. It can create weighted and unweighted cutflow objects to be picked up downstream by other xAH algos, and your own. The selection applied in data only is:

  • GRL (can be turned off)

  • LAr Error

  • Tile Error

  • Core Flag

In both data and simulation (MC), the following cuts are applied

For derivations, the metadata can be accessed and added to the cutflow for normalization. The parameters to control the trigger are described in this header file. If one wants to write out some of the trigger information into a tree using HelpTreeBase, flags must be set here.

Note

For MC only, the pileup reweight can also be applied.
