FLUKA: Problem

[foucher <yann.foucher@psi.ch>]

Dear Fluka users,

I would like to calculate the proton flux as a function of the radial
distance (from R=0. to R=10 cm).
For this purpose I use a USRBIN card.
There no material in my calculation and I have 10^6 incident proton.
My beam profil is gaussian in the x and y direction. I should have 10^6
proton in output
I have got a problem to understand the output of a USRBIN card.
Here is my USRBIN card:

USRBIN      17.         1.      58         10.        0.         2.

USRBIN      0.          0.       1.        100.       1.         1.
&

My question is what is the unit of such a card ?
How can I have the results in number of protons in each circular part of
the card.
