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?
The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“Since the drag coefficient C is ∼2 for roughly spherical spacecraft in low Earth orbit (L. Niccolai & G. Mengali 2024), and the density of the Martian exosphere at Phobos’s altitude is similar to the density of Earth’s exosphere at LEO altitude (N. Østgaard et al. 2003; P. D. Feldman et al. 2011), we set the drag coefficient C at 2.”

Experimental — accuracy not yet measuredThe cited source says what the claim attributes to it.
In the citing paper
“At Phobos’s distance from Mars’s surface, the main constituent of the exosphere is hydrogen (P. D. Feldman et al. 2011).”

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.
