... Fix $s$ with $Re (s)=\sigma$, and let $\chi$ run over all Dirichlet characters with (say) prime conductors. Then (generally conjecturally), $M_{\sigma}(z)$ (resp. $\tilde{M}_{\sigma}(z)$) coincides with the limit-average over $\chi$ of $\delta_z(L'(\chi,s)/L(\chi,s))$ (resp. $\psi_z(L'(\chi,s)/L(\chi,s))$). Here $\delta_z(w)$ is the Dirac measure concentrated at $z$ and $\psi_z(w)=\exp(i Re(\bar{z}w))$ is the additive character on the field of complex numbers parametrized by $z$. ...
