count.f is a special program to read trace information which in tern is
created by a special output from the trace routine (which is manually 
rewritten for this end; see ccc part in  eptrce of epgen.f.).

This is to prove that the number of particles at the shower maximum for
inclined showers is larger than the vertical ones; this seems to be
wrong at first glance but in low critical energy media, this really
takes place.  At 45 degrees, the shower max is about 30 % larger than
vertical one at several hundreds GeV showers.  To prove that this 
can happen, the trace information is specially taken (only for 
electrons with x, z).  The count.f sets arbitrary planes with an
arbitrary angle to the icident particle direction, and counts the
number of particles which across each plane.  Then there is no
ambiguity that the effect is produced by the wrong treatment of 
inclined showers.  Once a.out from count.f is invoked, you have to
put angle (0 is for vertical showers,  30 is for 30 degree zenith
angle).  a.out is assumed to read the trace info. in 'temp' in the
same directory.

Two figures are the results of 50 MeV e- and 500 MeV e- cases.

Note:the effect almost disappears when the minimum energy is high
(> 20 MeV) or when a critical energy is high (say, air or scinti).

For air, the number of particles may be taken as the same as vertical
ones even at 45 degrees.

Using numerical integration assuming the NKG-lateral distribution
we get factor ~0.9 at 45 degrees; i.e, we cannot get a larger number
for inclined showers. This may be due to the wrong lateral distribution.
This numerical integration is in the Test dirctory.


For 500 MeV, 200 events; we need 31 MB space for trace infomation.
