Page 24 - The model environments described in this section will be for energies above 4 MeV. The lower energy protons which extend throughout the outer zone will be treated at a later date. The satellite data that have been used in constructing the proton maps are given in Tables 6 and 7. We shall refer to the data by the code name given in these tables. For certain energy intervals and for large regions of space the integral spectrum can be represented by an exponential spectrum. To illustrate this point...

It has been found necessary to draw the BL flux map representation to show some of the inconsistencies that developed in selecting the B dependence. An iteration between the BL map and the FB plot produced a smooth representation in both systems that is consistent with the data. At some time in the future it may be feasible to obtain analytical fits but at present we feel the eyeball method is adequate...
