9714a029 | 6 | // |
1ceee0b9 | 7 | // This class allows to obtain Q_inv correlation function with weights |
8 | // calculated by Lednicky's alghorithm. | |
9 | // Numerator is filled with weighted events. Weights are attributed to reconstructed tracks. | |
10 | // Weights are calculated with corresponding simulated particles momenta. | |
11 | // Denominator is filled with mixing unweighted reconstructed tracks. | |
12 | // One needs both pairs | |
13 | // (simulated and recontructed), thus function is of class AliHBTTwoPairFctn1D. | |
