Resumen:
By means of Monte Carlo simulations of extensive air showers (EAS), we
have performed a comprehensive study of the shower to shower
fluctuations affecting the longitudinal and lateral development of EAS.
We split the fluctuations into physical fluctuations and those induced
by the thinning procedure customarily applied to simulate showers at
EeV energies and above. We study the influence of thinning on the
calculation of the shower to shower fluctuations in the simulations. For
thinning levels larger than R_thin = 10^-5 - 10^-6, the
determination of the shower to shower fluctuations is hampered by the
artificial fluctuations induced by the thinning procedure. However, we
show that shower to shower fluctuations can still be approximately
estimated, and we provide expressions to calculate them. The influence
of fluctuations of the depth of first interaction on the determination
of shower to shower fluctuations is also addressed.
