“The two clocks were separated in heights by ∆ h = 3250m, predicting a desynchronization of ∆ t/t ≈ g ∆ h/c 2 ≈ 30 . 6 ns d -1 , where g and c are the local gravity and the velocity of light in vacuum. The measurement gave (36 . 5 ± 5 . 8) ns d -1 , giving a relative accuracy of around 20%.”

In the citing paper
“Now, we can say that this experiment is amongst the first demonstration of chronometric levelling (see section 2.4): the clock comparison measured a difference of altitude between the two clocks of (3880 ± 620) m, to be compared with the otherwise measured value of 3250 m.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
