  1. The uncertainties expressed in parentheses represent one standard deviation, obtained as the quadrature sum of the statistical and systematic uncertainties (for experimental values), or the estimated systematic uncertainty (for theoretical values). The deviation \(\Delta\) between the frequencies is calculated by subtracting others’ data from our value. The combined uncertainty \(\sigma\) is calculated as the quadrature sum of the uncertainties of the two measurements. Note: it is a coincidence that deviations equal uncertainties.
