Comparing simulated dispersion relations to experimental Silicon data

[lylos]

I have three different plots for the dispersion relation of Silicon. How can I compare the two plots that I have generated to the plot of the experimental data? I remember that I had to do this last semester, but I don't remember what it was called.

Ok, maybe finding the correlation coefficients for each plot may be my best bet in this situation. Anyone know?

Are there some parameters involved in the generated (non-experimental) plots? How about doing a least-squares fit where you adjust those parameters?
