Longitudinal profiles of intensities (top panel) obtained for 1 MeV protons at θ = 90° and r = 1.0 au. The intensities obtained in the Icarus wind are represented by dotted lines, while the EUHFORIA-based trends are depicted by solid lines, each in their respective colours. Similarly, the solar wind speed and solar wind particle number density (middle and bottom panel, respectively) are shown in dotted lines for Icarus and solid lines for EUHFORIA.
