{\bf Theoretical uncertainties}  The dominant systematic uncertainty is of theoretical nature. The total event rate indeed requires an accurate prediction of the total cross section for top pair production. This The precision of this  prediction is inferred to be at the level of a few per-mil per mil  in Ref.~\cite{Amjad_2013} for $\sqrt{s} = 500$\,GeV. A similar precision can be expected at smaller centre-of-mass energy as long as it is significantly above the production threshold.  {\bf Integrated luminosity profile}
