Pressure evolution of various quantities. The SC muon depolarization rate σ _SC, magnetic penetration depth λ _eff and the superfluid density n _s/m*m _e (a) as well as the zero-temperature gap values Δ_1,2(0) (b) are shown as a function of hydrostatic pressure. Dashed lines are guides to the eye and solid lines represent linear fits to the data. The error bars represent the s.d. of the fit parameters. c A plot of T _c vs. ${\lambda }_{\mathrm{eff}}^{-2}\left(0\right)$ obtained from our μSR experiments in MoTe₂. The dashed red line represents the linear fit to the MoTe₂ data. The Uemura plot for various cuprate and Fe-based HTSs is also shown^{49, 66–70}. The relation observed for underdoped cuprates is also shown (solid line for hole doping^55–59 and dashed black line for electron doping⁶¹). The points for various conventional BCS superconductors and for NbSe₂ are also shown
