Extended Data Fig. 4: Investigation of the quadratic Zeeman shift.
The magnetic field dependences of \(\delta {\nu }_{431}^{A,174}\) are shown, where A = 168 (a), 170 (b), 172 (c), and 176 (d). Points and error bars denote the mean values and the 1σ statistical uncertainties, respectively, with the latter derived from the overlapping Allan deviations. Green shaded regions represent the average of error bars, while orange shaded areas denote the standard deviation of three or four data points.
