Caption: Figure 2.
Figure showing (left ordinate) the scaled radial component of the magnetic field r2BR(r) as a function of degrees from perihelion for E04–E23. The corresponding hammerhead occurrence fraction from hampy is plotted as the gray histograms in the background (right ordinate). The histograms are normalized to the unit area for each encounter. This figure was generated using Plotbot, an open-source Python package (R. Alexander & J. Verniero 2026).
