Query: Deuteron charge radius and Rydberg constant from spectroscopy data in
  atomic deuterium   We give a pedagogical description of the method to extract the charge radii
and Rydberg constant from laser spectroscopy in regular hydrogen (H) and
deuterium (D) atoms, that is part of the CODATA least-squares adjustment (LSA)
of the fundamental physical constants. We give a deuteron charge radius Rd from
D spectroscopy alone of 2.1415(45) fm. This value is independent of the
measurements that lead to the proton charge radius, and five times more
accurate than the value found in the CODATA Adjustment 10. The improvement is
due to the use of a value for the 1S->2S transition in atomic deuterium which
can be inferred from published data or found in a PhD thesis.
