    • It is only appropriate to swap defects to hydrogen sites at the same energy. The distribution of possible defect energies makes it incorrect to swap the integrated defect density over the integrated density of hydrogen sites as done by Winer in Ref. [4].

    • We have assumed that both defects have the same average energy. If we were to have statistically independent defect energies, as was done by Schumm and Bauer in Ref. [5] then we would be minimizing the energy of a pair of defects, which would only apply if they were intimately paired.

    • It is possible to solve this integral exactly, with the result that the factor of 2Ev02/ [ 2 Ev0- kT ] in Eqs. (11) and (12) would be replaced by π k T / lcurl 2 sin ( π k T / [ 2 Ev0] ) rcurl. The correction is of order 12%, which is far less than the experimental uncertainties in other factors (such as Nv0).

    • The temperature independence of the electron spin signal shows that U > 0.1 eV [see, and references therein]. Many other experiments to determine U need to be reinterpreted in light of the defect pool model.
