Fix FusedSilica and FakeFusedSilica refractive indices #217

Closed soleti closed 9 months ago

soleti commented 9 months ago

This PR fixes issue #216. Now, the refractive indices for FusedSilica and FakeFusedSilica are calculated only up to 10.7 eV, which is the upper limit for the formula used in the code.

The problem is that we can have photons with higher energies simulated (e.g., Cherenkov photons), so we should define a refractive index up to 11.5 eV in some way. Are there not any measurements at that energy?

I see, then maybe setting the refractive index between 10.7 and 11.5 eV at the value obtained at 10.7 eV? I couldn't find measurements below 115 nm (which is 10.7 eV).

Fine for me!
