The optical conductivity spectra are determined with the Kramers-Krönig transformations from the measured reflectivity spectra, where the formalizations are given in the next section. Errors in the optical conductivities (real and imaginary) and superfluid densities are determined with the recalculations from the reflectivity spectra after the errors are included. One of the recalculated spectra for the real optical conductivity, as well as the relative error is given in Fig. 3.12. In the next chapter, the temperature dependence of the superfluid densities is given with the error bars in Fig. 4.​21. As can be seen from the figures, the errors on the calculated superfluid densities have no effect on the obtained temperature scales.

Fig. 3.12Optical conductivity has been determined from the reflectivity measurements with Kramers-Kronig transformation. After the calculated error bar is added to the reflectivity, the optical conductivity recalculated with the same method. And the difference between two calculations are determined as the error on the optical conductivity
