  4. Energy Reconstruction • Energy is reconstructed with 5X5 cluster • Raw Data: two deep statistics runs. • PWO-4280, • Glass-4279

  5. Fitting Function • Partial Gaussian • Fit the peak with single Gaussian function in the range (-2σ,1σ) from the Maximum • Landau*Gaussian • Fit with Landau Gaussian convolution function A: Normalization Coefficient P: Position of Maximum W: Width of Landau function σ: Sigma of Gaussian function
