Actually, "public domain" is a US concept that doesn't apply elsewhere.
Better would be a statement saying that blanket permission is given for
these files to be copied. One of the Creative Commons Licences would appear
to be the right tool for the job.

> IERS, it would seem that this should not be an issue.  It's pretty likely that the absence of a statement in the files is an oversight, perhaps caused by an assumption that absence of a stated restriction means there isn't a restriction.  (But in fact, absence of statement means no permission -- it doesn't mean no restriction...)

Actually, absence of statement means simply that no statement has been
made. After all, permission can be granted in other ways. Perhaps there's a
notice up in their offices :-)
