During a recent comprehensive analysis of the pitch angle distributions of energetic particles in Jupiter's magnetosphere we found an intermittent error in our Pioneer 11 data reduction software. When present, this error caused a phase shift of 180¿ in the assignment of spacecraft roll angles. The corrected analysis reveals significant proton anisotropies directed toward the planet in the southern hemisphere, contrary to our previous report. In the northern hemisphere both proton and electron anisotropies are directed away from the planet, as reported previously. Hence, our earlier claim of direct evidence for the hypothesis of recirculation of energetic particles in the Jovian magnetosphere is invalidated. Nonetheless, we consider that the hypothesis continues to have merit on the basis of indirect evidence, though the recirculation process must be weaker than envisioned originally and obscured by other processes.
