What do you mean by the 'observed path'? What you are providing is the mean-free-path photons will have as a function of their energy. This doesn't mean that the actual path sampled for a particular photon trajectory comes out to be exactly that mean. What you should be getting, if you average over many photon path histories at a given energy, is what you've put in.

I noticed that you are providing the property vector in decreasing energy since your input is in increasing wavelength. I don't think this should be a problem but you might want to reverse the order.

I am surprised at that since even if you give one and the same value for all energies, an actual sampled path length should still only average to the value you provided.
