SWAP Pickup Ion Data Release (2021)

New Horizons’ Solar Wind Around Pluto (SWAP) instrument has been measuring interstellar H pickup ions (PUIs) out to ~47 au from the Sun. These measurements have led to numerous discoveries of the interstellar PUI distribution, their behavior at interplanetary shocks, and extrapolation of PUI properties to the heliospheric termination shock. This data release improves upon and extends prior analyses of interstellar PUI measurements out to ~47 au and should serve as the primary interstellar PUI data set for the heliospheric community. A detailed description of the measurements, methodology, and analysis results can be found in McComas et al. (2021).
