\label{fig:GFitter1} The 68\% C.L. contour from the fit of all Electroweak precision measurements from TLEP-Z  (red curve) in the $(m_{\rm top},m_{\rm W})$ plane, should the relevant theory uncertainties be reduced to match the TLEP experimental uncertainties, compared to the direct W and top mass precisions (blue curve) expected at TLEP-W and TLEP-t. For illustration, the LHC (black curve) and ILC (green curve) projections for the direct $m_{\rm W}$ and $m_{\rm top}$ precisions are also indicated, as well as the current precision of the Tevatron measurements (dashed curve). The purple line shows the prediction from the Standard Model for $m_{\rm H}=$ 125~GeV. The value of the Tevatron W mass was modified in this figure to match the SM prediction for $m_{\rm top}=$ 173.2~GeV. The thickness of the Standard Model line result from the measurement of $ m_{\rm Z})$ at TLEP, it would have a thickness of 2.5 MeV for LHC or ILC on their own.
