TOA (modulated) fluxes (times ) as a function of the kinetic energy per nucleon, for p and He. The symbols are black circles for AMS-01, red squares for BESS-98, and blue triangles for BESS-TeV. The curves correspond (for the four models of Table 2) to the best-fit spectra obtained by a fit on the AMS-01 data (top panel), BESS98 data (middle panel) and BESS-TeV data (bottom panel).
