  1. The parameters of the fit to \(\frac{\kappa }{T}={a}_{2}{T}^{-2}+{a}_{1/2}{T}^{-1/2}\) plotted in Fig. 4a. Also listed are a1/2 according to Eq. (4) (with no adjustable parameter) and previous experimental and theoretical reports on the magnitude of the prefactor of the quasi-particle contribution, a2[ ≡ κT].
