The zenith angle dependence
Black: cos(zenith angle) < 0.2
Blue: 0.2 < cos(zenith angle) < 0.4
Red: 0.4 < cos(zenith angle) < 0.6
Magenda: 0.6 < cos(zenith angle)< 0.8
Water: 0.8 < cos(zenith angle) < 1.0
Horizontal particles loose the energy at high energy.
This is probably due to limited simulation volume (880m radius),
but I think this is
fine because those particles beyond the volume will not make so many
photons that can reach our detector, but I will check this more.

There is a constant energy loss during the propagation
from surface to the detector (~log10(0.2)~30%)
