Table 4.

Values of the top quark pole mass $m_{\mathrm{t}}^{\text{pole}}$ and strong coupling constant ${\alpha }_S(m_{\mathrm{Z}})$ used in the different PDF sets. Also shown are the corresponding $m_{\mathrm{t}}(m_{\mathrm{t}})$ values obtained using the RunDec  [83, 84] conversion, the number of loops in the conversion, and the ${\alpha }_S$ range used to estimate the PDF uncertainties
