16.8} Example of input data cards


 An example of user data cards to run a FLUKA cosmic ray problem is shown in
 the following, with some comments on the relevant points. The example refers to
 the simulation at geographical coordinates of 36.0 degrees North Latitude
 and 140.0 degrees East Longitude, using the solar modulation of Dec. 23rd
 1995.
