The data contains parameters and errors of Drude-Lorenz fits to the complex dielectric permittivity data of gold, silver, and copper. It also contains the program for fitting user supplied permittivity data with the Drude-Lorenz model.
These data are presented in the publication "Optimizing the Drude-Lorentz model for material permittivity: method, program, and examples for gold, silver, and copper", Phys. Rev. B 95, 115444 (2017) - http://dx.doi.org/10.1103/PhysRevB.95.115444
