Maps of the particle back-tracing of ions measured by FIPS (colored lines), with the inner and outer gray lines showing the location of the magnetopause and bow shock respectively. In all cases, the particles are traveling toward the spacecraft and the arrow is an example of that direction. a Shows the X’-Z’ plane, and (b) shows the Y’-Z’ plane. Source data are provided as a Source Data file.
