Relative particle flux intensity (normalized to intensities at 1 au) as a function of radial distance from both SIS-ULEIS (red, 226−320 keV/nuc 4He) and from Van Hollebeke et al. (1978) (blue, 0.9−2.2 MeV H). The dashed line is included as a visual guide for comparing data points in the inner heliosphere.
