LVL1::gFEX Namespace Reference

Enumerations
enum class	FPGA { A , B , C , N_FPGAS }

Functions
FPGA	getFPGA (float eta)
	Get the FPGA code from the tower eta.
std::string	FPGAToString (FPGA fpga)
	Get the name of an FPGA.
FPGA	FPGAFromString (std::string name)
	Get the enum from the name of an FPGA. Returning N_FPGA means that the string wasn't correct.
float	towerArea (float eta)
	Get the GCaloTower areas from their eta bins.
