As mentioned in the Section~\ref{sec:sensitivities}, the dominant systematic error on these numbers is the theoretical uncertainty on the predicted event rate. It is difficult to say today what this uncertainty will be at the FCC-ee startup. To evaluate its effects, the likelihood in Eq.~\ref{eq:like} Eq.~\ref{eq:likelihood}  was enhanced with the corresponding nuisance factor, and the form factors were determined for any value of the assumed cross-section theorerical error. The result is displayed in Fig.~\ref{fig:crosserr}.
