Table 3.

The absolute uncertainties in $m_{\mathrm{t}}^{\mathrm{MC}}$ and their sources, from the simultaneous fit of ${\sigma }_{\mathrm{t}\overline{\mathrm{t}}}$ and $m_{\mathrm{t}}^{\mathrm{MC}}$. The MC statistical uncertainty is determined separately. The individual uncertainties are given without their correlations, which are however accounted for in the total uncertainties
