\section*{Introduction}
The present situation is the following: we use the files sploptiplusmauro.dat (sploptiminusmauro.dat) which are fluxes ($dN(E)$) expressed in terms of numbers of neutrino species per $100 m^2$ per year and binned every $BWF\equiv0.02GeV$ and computed at $L=130km$.

Internally, GLoBES v2.0.11 uses these fluxes with some {\it a priori} and at the end of the day it turns out that:
\begin{equation}
        dN(E)\times \frac{1}{L^2} \times \mathrm{norme2}(0) \times \mathrm{@norm} \times \Delta T
\end{equation}
with $\mathrm{norme2}(0) = 5.198927 = 6.02204 10^{-12}\ 295^2\ 9.92033 10^6$ the result of a function in \verb|glb_fluxes.c|.
