Assuming the total neutrino flux is proportional to the $\cos$ of the angle with which they are created and the energy of the beam,  \begin{equation}  \begin{split}  &  d^2 N \propto d \cos \theta d E_{\nu} \\  \implies & \frac{d^2 N}{d \cos \theta d E_{\nu}} \propto 1  \end{split}  \end{equation}  From the point of view of an observer in the lab, the total flux at a given angle and energy can by found using the relation
