Stability analysis of the French timescale UTC(OP)
This paper presents the current results obtained with the new version of the French timescale UTC(OP) in operation since more than two years now. The time scale is based on an hydrogen maser steered by one of the SYRTE atomic fountains. Thanks to this technique, UTC(OP) is one of the best real time realization of UTC. A statistical analysis of different UTC - UTC(k) comparisons is presented.
