Comparison of methods for simulating equatorial scintillation in the presence of EPBs: (a) GISM simulation yielding the background scintillation values, (b) and (c) GISM simulations with the additional phase gradient screens. The difference between (b) and (c) is related to the masks used (shown as gray areas on the background). While (b) uses a simple binary mask that determines the irradiance regions with a single threshold level of 120 Rayleigh, the mask in (c) uses two thresholds at 120 and 10 Rayleigh in order to incorporate some EPB morphology between two crests of ionization.
