All papers · ⁸⁸Sr⁺ optical clock with 7.9×10⁻¹⁹ systematic uncertainty and measurement of its absolute frequency with 9.8×10⁻¹⁷ uncertainty
Fractional frequency deviation $y$ /$10^{-15}$ from the 2021 CIPM recommended value against MJD $-$ 60459, for the 5 d periods (dots) and the months (circles), both with error bars, and the full 10 months as a shaded $\pm1\sigma$ band. Vertical lines separate the Circular T periods 438 to 447; the period numbers printed above the data are not drawn.
This panel was computed from the authors' public data deposit (Zenodo: https://doi.org/10.5281/zenodo.17070662, CC BY 4.0), with the 10-month band 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.
