Optical data for Cu2O, CuO and Cu in the 1 eV to ~ 100 eV energy range

Our optical data in (J. Phys.: Condensed Matter.24 (2012) 175002; DOI10.1088/0953-8984/24/17/175002) for Cu2O, CuO, and Cu in the 1 eV to ~ 100 eV energy range has received a strong and continued interest and we have had requests to share the data in digital form.

Here we therefore make the data available for n and k in Fig. 8 of the paper in two Excel files.
