Normalization of nonzero dynamo coupling coefficients ($c_1=1,|c_3|=1$)

For nonzero coefficients of $A^{\ast }V$ in $\dot{B}$ and $AB$ in $\dot{V}$, a relative phase rotation makes $c_1$ real positive. Positive rescalings of $A,V,B$ then normalize both magnitudes to one. The phase of $c_1{c}_3$ is invariant under these rescalings and remains as the phase of normalized $c_3$. Zero couplings cannot be normalized to one; they are degenerate parameter cases.
