Enum documentation

enum TFCSHistoLateralShapeParametrization::FCSStatusBits

Status bit for FCS needs.

Enumerators
k_phi_symmetric

Set this bit to simulate phi symmetric histograms.

Function documentation

void TFCSHistoLateralShapeParametrization::set_geometry(CaloGeo* geo) override

will actually not store the geometry information, but rather used to check the validity of the 2D shape histogram

double TFCSHistoLateralShapeParametrization::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 TFCSHistoLateralShapeParametrization::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

bool TFCSHistoLateralShapeParametrization::Initialize(TH2* hist)

Init from histogram. The integral of the histogram is used as number of expected hits to be generated
