Figure 1: The time differences in ns of the 4 atomic clocks during the total eclipse. Rb-Cs(FTS), Cs(FTS)-H, H-Cs(HP), Cs(HP)-Rb are the time differences between two cesium clocks Cs(FTS) and Cs(HP), a rubidium clock Rb, and a hydrogen maser H. The last plot shows a clear linear drift that has been removed to obtain the red curve for which the red tick marks on the right side apply. The marks b and c label the beginning and the end of the total eclipse.
