= Normalization of nonzero dynamo coupling coefficients
{title2=$c_1=1,\quad |c_3|=1$}

For nonzero coefficients of $A^*V$ 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 $c_1c_3$ 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.
