48. Note the discrepancy with Ref. 14, where the authors seemingly fail to distinguish between D and D̃. In any case, their quoted estimate (D/J=0.35 using the symmetric definition of J) is hard to reconcile with the very small anisotropy of critical field and gap energies that the authors report and that our neutron-scattering experiments confirm. We believe that the discrepancy is due to inconsistent notations or a trivial mistake in Ref. 14.
