Detailed Description

Class that sorts electron candidates.

\Class L1GctElectronSorter This class can be constructed to sort iso or non-iso electron candidates. The electrons are sorted in ascending order and the 4 highest in rank will be returned. It represents the 1st stage sorter FPGA's on the electron leaf cards.

◆ setupObjects()

Create a null input electron with the right bunch crossing, and fill the input candidates with copies of this.
