RPC-ICA-derived characteristics of the local solar wind ion distribution functions at comet 67P during the Rosetta mission (2014–2016) for H⁺, He²⁺, and He⁺. (A) Density n_i, (B) mean ion speed U_i, and (C) ion flux F_i. The SWIC is approximately indicated as a gradually deeper gray region; its position with respect to the spacecraft is likely highlyvariable. All quantities have been submitted to a one-day moving average to remove variations due to the nucleus rotation. Increasingly intense colors indicate an increasing number of data points.
