Momentum flux for the magnetic field, cometary ions (H₂O⁺ group ions) of all energies and solar wind ions (H⁺, He²⁺, and He⁺) for the entirety of the Rosetta escort phase. Each point is the average of 12 h of data (the rotation period of the comet) to eliminate any effects due to asymmetrical outgassing. The dashed line indicates the heliocentric distance of the comet. The two case study dates are marked by vertical red lines.
