Comparison of the model fluxes with threshold of Voyager 1/2 (st = 1.2μm), Pioneer 10 (st = 4.5μm), and Pioneer 11 (st = 8.7μm) with the fluxes measured by Voyager 1 (filled circle) and 2 (open circle) and Pioneer 10 (filled square) and 11 (open square). The solid line labeled “w/o threshold” shows the model flux without the threshold. The dotted lines show the flux of interstellar dust for the threshold of the above spacecraft.
