This class is used to compute the \(C\) parameter of CPV in \(M \to V \gamma\) in terms of the helicity amplitudes \(H_V^{(+,-)},\overline{H}_V^{(+,-)}\), computed in the MVgamma class:

\[ C = \frac {( |H_V^+|^2 + |H_V^-|^2 - |\overline{H}_V^+|^2 - |\overline{H}_V^-|^2)}{( |H_V^+|^2 + |H_V^+|^2 +|\overline{H}_V^-|^2 + |\overline{H}_V^-|^2)} \,. \]
