When a figure we published turns out to be wrong, or the underlying record is revised, the correction is recorded here and kept permanently. The original article keeps its original text, so the record of what we said and when stays intact. This page is the one place to look to find out whether something we published has changed.
Nothing published on this site has needed correcting yet. This page is kept here, and linked from every data page, so that there is one permanent place to check. An empty log is a statement, not an absence of one.
Tell us and we will check it against the records and publish the result either way, including when the result is that our figure stands. A disagreement we cannot resolve gets stated as a disagreement rather than quietly dropped.
