In 19 upright ctenophore cilia records, imaging plane could not be separated from recording date

We tested whether released cilia recordings support a link between statocyst wiring and a difference between imaging planes. We used 19 upright records from a fixed source version. We reproduced all 18 finite published correlations, with maximum error 1.11e-16. The metadata assign eight tentacular records to two samples on one date. Eleven sagittal records came from eight samples on seven other dates. With one mean per sample and intact 20-second windows, the tentacular-minus-sagittal correlation difference was 0.341. A nominal 95% Welch interval was -0.516 to 1.198. This interval assumes independent sample means and a Student approximation. More directly, the tentacular-plane indicator equals the 1 August 2023 date indicator. The matrix for eight date effects plus plane has rank eight, not nine. Thus, a model with free additive date effects cannot give a unique plane effect. A stated count-weight model also shows that input overlap alone is not a quantitative account of the observed order. These results limit a specific structure-function inference. They do not show equal function between planes or exclude neural coordination. The package contains source data, hashes, new code, all results, figures, and reproduction instructions.
