## Main Question or Discussion Point

Hi,

The Gaisser parametrization is something like:

[tex]\Phi_0(E,\theta)=AE^{-\gamma}\left[ \frac{1}{1+1.1E\cos(\theta)/E_{\pi}}+\frac{0.054}{1+1.1E\cos(\theta)/E_K} \right] [/tex]

where [tex]A,\gamma,E_{\pi},E_K [/tex] are constants. My question is: Is this saying that at higher zenith angles the flux of muons is stronger? Is there a reason for this?

Also, would this say that the intensity would be higher at an angle than at vertical for muons crossing the same opacity(=distance)?

Any input would be appreciated.

Thank you,

Safinenko
