Upper panel: flux spectrum of Epoch 3 fit with SYNAPPS algorithm. The flux spectrum is shown with a black solid line, and the SYNAPPS fit is shown as a red dashed line. Fit parameters are listed in Table 2. Lower panels: polarization and ﹩\theta ﹩ spectra compared against individual ions from SYNAPPS fits for Epoch 3. The ion flux values are plotted to different scales, as shown on the right-hand axis. See text for explanation of A, B, C, and D labels.
