Function documentation

double TFCS2DFunctionLateralShapeParametrization::get_sigma2_fluctuation(TFCSSimulationState& simulstate, const TFCSTruthState* truth, const TFCSExtrapolationState* extrapol) const override

default for this class is to simulate get_number_of_expected_hits() hits, which gives fluctuations sigma^2=1/get_number_of_expected_hits()

FCSReturnCode TFCS2DFunctionLateralShapeParametrization::simulate_hit(Hit& hit, TFCSSimulationState& simulstate, const TFCSTruthState* truth, const TFCSExtrapolationState* extrapol) override

simulated one hit position with weight that should be put into simulstate sometime later all hit weights should be resacled such that their final sum is simulstate->E(sample) someone also needs to map all hits into cells
