Primary cosmic rays may account for a substantial fraction of the observed counts. A significant secondary contribution is also implied, however there is currently no modeling to suggest to what extent this contributes to the observed counts. Some ESP channels appear to saturate at 4 x 10^4 counts/ s. The reported flux levels should not be used as absolute measures: It is known that ESP yields lower fluxes and harder spectra than SOPA, in the region of overlap between the detectors. Calculation of spectra, for example, would not be meaningful for this data set – especially as the data are daily averaged and merged from several satellites."
