In the version of this article initially published, the definition of the Allan deviation shown in equation 6 originally omitted “ \(\frac{1}{{f}_{0}}\times \) ” and the square root symbol on the right-hand side of the equation. The error has been corrected in the HTML and PDF versions of the article.
