All papers · ⁸⁸Sr⁺ optical clock with 7.9×10⁻¹⁹ systematic uncertainty and measurement of its absolute frequency with 9.8×10⁻¹⁷ uncertainty
Monthly Sr$^+$ values $y$ /$10^{-15}$ against MJD $-$ 60459 with total uncertainties as error bars (circles), compared with interpolated values with extrapolation uncertainties as error bars (diamonds); the two are offset horizontally for clarity, as printed.
This panel was computed from the authors' public data deposit (Zenodo: https://doi.org/10.5281/zenodo.17070662, CC BY 4.0), with the extrapolation uncertainties recovered from the published vector figure. The plot shown here is re-rendered for interactive viewing and analysis. See the paper for the original figure and full scientific context.
