This class is used to compute the binned observable \(<P_3^{CP}>\) in \(M \to V l^+l^-\) in terms of the binned CP asymmetry helicity coefficients \(<\Delta_i>\) and the CP average helicity coefficients \(<\Sigma_i>\), computed in the MVll class:

\[ <P_3^{CP}>= -\frac {<\Delta_{9}>}{4<\Sigma_{2s}>} \,. \]
