Figure 2:   The time differences in ns of the 4 atomic clocks during the total eclipse observed over a longer period. Different offsets have been subtracted from each plot. The clearly visible drifts (black curves) have been removed as a quadratic function to obtain the red curve for which the red tick marks on the right side apply. The marks a and d label the beginning and the end of the partial eclipse. The strong anticorrelation of trace A and B shows that the Cs(FTS) clock dominates the noise at this time scale. H and Cs(HP) are both very stable and agree very well so that no regular drift could be identified.
