Data Set Abstract This data set contains ion and electron flux, as a function of energy and angle, and ion time of flight measurements of ion composition. These data were measured by the Plasma Instrument for Planetary Exploration (PEPE) on the Deep Space 1 (DS1) spacecraft during the DS1 encounter with comet 19P/Borrelly. PEPE measured particles from 8 eV to 31.5 keV and over a 2.8 pi sr range of angles. These data were acquired in order to characterize the interaction between the solar wind and a moderately active comet, including but not limited to the slowing and heating of the mass-loaded solar wind, the composition, abundance and velocity distribution of cometary heavy ions, the location and properties of boundaries such as bow shocks and the cometopause, and changes in the charge state of solar wind heavy ions caused by charge transfer reactions with the neutral coma.
