Best-fit Propagation Parameters for I- and P-Scenarios

Parameter Units Best Value Error
z h kpc 4.0 0.6
D0(R = 4 GV) cm2 s−1 4.3 × 1028 0.7
δ a 0.415 0.025

The P-scenario assumes a break in the diffusion coefficient with index δ1 = δ below the break and index δ2 = 0.15 ± 0.03 above the break at R = 370 ± 25 GV; see the text for details.
