Particle flux ratios during the Rosetta mission 2014–2016. (A) Helium species. The 1 h averaged He+ /He2+ ratio measured by RPC-ICA (black) is compared to the daily averaged analytical forward model solution (blue), with mean speed Usw = UICA(He2+). The column density is derived from ROSINA data. Modeled He0/He2+ flux ratios are shown in red. (B) Hydrogen species, with modeled H0/H+ (blue) and H/H+ (red) ratios for a solar wind mean speed of Usw = UICA(H+). The solar wind ion cavity is designated as a gradually denser gray-shaded region. Safe mode and excursions where ROSINA data were excluded from the analysis are indicated.
