What is recorded here?
McGuirk and colleagues operated two light-pulse atom accelerometers as a gravity gradiometer. They characterized common-mode vibration rejection and measured a tidal acceleration signal, and presented interference fringes and tests of sensitivity to platform motion. A source archive supplies the eleven original figures missing from the generated preprint PDF.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The actual apparatus separation was approximately 1.4 m. The abstract’s sensitivity and accuracy expressed for a 10 m baseline are scaled or inferred, not demonstrated with a 10 m instrument. Accuracy is inferred from tidal-model comparisons over limited runs and is not independently validated here. An earlier 1998 atom-gradiometer demonstration is a separate contribution. Separate experimental data and simulation replay, individual full-name identity mapping, and final published-version comparison remain open.
