All n-k-Data tables consist of three columns. The first one contains the wavelength in micron (in the case of the Mg/Fe sulfides centimeter). The second one is the real part of the complex refractive index (n), the third one is the imaginary part (k). Values in brackets given after the chemical formulae are the material densities (if available).


For the details of the derivation of all n-k-Data I refer to the mentioned publications (see the List of Publications).
