calculate()

		const unsigned int	runnumber,
		const double	cluster_eta,
		const double	et,
		Result &	result,
		const bool	onlyTotal = false ) const

The main calculate method: dataType PATCore::ParticleDataType::DataType (e.g DATA,FULL etc) @ runnumber the run number.

1st dimension of the stored measurements @ cluster_eta the cluster eta. 2nd dimension of the stored measurements @ electron et. third dimension of the stored measurments @ result struct filled with SF, Total uncertainty, Stat uncertainty, Uncorr uncertainty @ onlyTotal do only the "total" systematic returns 0 in failure

Toy production is controlled by internal flags set by the Asg Tool. As toys are special.
