Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • N atoms from N2 photolysis in the upper atmosphere can mix to lower levels and react with CH4 photolysis products to make HCN.

    “In particular, N atoms from N2 photolysis in the upper atmosphere can mix to lower levels and react with CH4 photolysis products to make HCN (166, 167).”

    From The Archean atmosphere (2020) · cites this paper as [167]

  • At Archean biogenic methane levels of ~10^3 ppmv, HCN concentrations reach ~10^2 ppmv.

    “At Archean biogenic methane levels of ~103 ppmv, HCN concentrations reach ~102 ppmv.”

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.
