Entanglement-Enhanced Optical Ion Clock
Fig. 3, panel (3)
Fractional stability of the $^{40}\mathrm{Ca}^+/^{87}\mathrm{Sr}$ frequency ratio, OADEV $\sigma_y$ against averaging time $\tau$ (s), at 250 ms interrogation time for the enDFS (red) and ccDFS (blue) schemes. Filled markers are the data range taken for the stability fit, open markers the rest; as printed, ccDFS has no markers at $\tau = 9$, 12 and 16 s. Error bars are smaller than the symbols.
