The IAU Resolutions on Astronomical Reference Systems, Time Scales, and Earth Rotation Models (Draft 4)
Abstract
The chapters in this circular reflect the six main subject areas described above. Each of the chapters contains a list of the relevant IAU resolutions, a summary of the recommendations, an explanatory narrative, and, in most chapters, a collection of formulas used in implementing the recommendations. The references for all chapters are collected in one bibliography at the end of the circular.

In the citing paper
“The GCRS also provides the foundation for the International Terrestrial Reference System (ITRS), and both systems differ by just a (time-dependent) spatial rotation (or a series of rotations); accordingly the ITRS coordinate time coincides with TCG (e.g.Soffel et al. 2003;Kaplan 2005).”

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.
