3. Higher order of scatter
I have to repeat the method 2 times:
Dprim
→ S1sc
→ CC with h1sc
→ D1sc
D1sc
→ S2sc
→ CC with Hmsc
→ Dmsc
An analogous recursive equation applies
with the difference that Hmsc is better fit
by a bi-exponential function
Additional input is required to calculate
inhomogeneity corrections: the energy
spectrum of msc photons generated at each
point
