The $\mathrm{s}$ quark distribution (upper) and the strangeness suppression factor (lower) as functions of x at the factorization scale of 1.9$\text{Ge}$ ${}^2$ (left) and $m_{\mathrm{W}}^2$ (right). The results of the current analysis are presented with the fit uncertainties estimated by the Hessian method (hatched band) and using MC replicas (shaded band)
