Abstract
In this work a statistical analysis of individual H-Masers is presented to optimize the prediction and weighting algorithms used for the generation of UTC. The H-Masers have been grouped by manufacturers' model to identify common signatures and statistical similarities. This allowed the agreement of the weights associated with the clocks in UTC to be checked with the output of this statistical analysis.To confirm these results a statistical analysis of the weighted residuals of the real and the predicted values of [(EAL-clocks)-(EAL-clocks)'] of each clock has been performed for several calculation months. This allowed an estimate of the stability of EAL (the component impacted by the clocks) to be made and a determination of the clocks which were impacting UTC more negatively. This study identified where improvements to the contribution of clocks in UTC could be made, and where problems and possible solutions lie.
