This PDEFoam variant stores in every cell the average target fTarget (see the Constructor) as well as the statistical error on the target fTarget.
It therefore acts as a target estimator. It should be booked together with the PDEFoamTargetDensity density estimator, which returns the target fTarget density at a given phase space point during the foam build-up.
