ROOTPWA is a toolkit for partial-wave analysis of multi-particle final states produced in high-energy particle reactions. It is used to determine hadron spectra from experimental data.
The two entries of the Jacobian matrix of the phase corresponding to the derivative with respect to real and imaginary part of the spin-density matrix were swapped.
