Calculated CR proton spectra (multiplied by E²) at four different positions along the Sun’s orbit (see Fig. 1 for the respective locations) in the Galactic plane (z = 0), where 90° corresponds approximately to the current solar system position and 126° is inside of the Saggitarius arm. The upper panel shows the spectra for isotropic diffusion, while the middle and lower panels include anisotropic diffusion with ϵ = 0.1 and ϵ = 0.01, respectively. The latter spectra have been rescaled by factors of 0.15 and 0.05 to account for the higher overall flux due to the stronger confinement in the disk in contrast to the isotropic case. The LIS from Webber & Higbie (2009) is plotted for comparison (black crosses).
