Performance and Characterization of U.S. Naval Observatory Clocks

Lee A. Breakiron, Demetrios N. Matsakis

Abstract:	Six years of U.S. Naval Observatory clock data are analyzed to determine the optimal data filter length and the amplitude and frequency of occurrence of statistically significant changes in the frequencies and frequency drifts of cesium-beam frequency standards and hydrogen masers by means of relative and correlation-corrected N-cornered-hat analyses of the frequency stabilities of postprocessed mean timescales. The effects of temperature and humidity on cesium and maser frequencies and drifts are also investigated.
