  1. Lateral disribution and energy determination along the ankle Germán Ros Magán & GMT

  2. The interpolated signal at a fixed distance from the core may be used as an energy estimator

  3. E= 30 EeV  = 45o footprint LDF & actual signal

  4. One realization of an LDF reconstruction

  5. ropt between fits and true LDF among fits Several realizations of LDF reconstruction

  6. ropt as a function of array spacing

  7. Asymmetric errors Fixed ro Fixed ropt

  8. A toy spectrum

  9. The spectrum can be affected

  10. From a) to f): Fist row is for E(ropt), the second row is for E(600) with saturated events and the third row is for E(600) without saturated events; left column are the symmetry of the distributions comparing their high and low sides (Gaussian H=L = 1) and right column are the tails of the distributions comparing their C.L. at 68% and 95% (Gaussian 95=68 = 2). (g) reconstructed energy bias. (h) fraction of saturated events. ropt r600 r600 w/o satturated stations

  11. Spectrum input (black) with the same statistic as AGASA and the reconstructed one obtained using S0(600) (S(ropt)) as energy estimator in blue (red). The vertical axis is multiplied by E3. Error bars are the CL at 68 and 95%.

  12. Input structured spectrum (black) and the reconstructed spectra using S0(600) (blue) and S(ropt) (red) as energy estimator note the position of the ankle and the GZK transition.
