Simulated time profiles for a level of density fluctuations ϵ = 0.8, an emission source located at θ₀ = 10°, an emission frequency of f = 35.2 MHz, f/f_pe(r₀) = 1.10, and anisotropy α = 0.1 (left column), 0.2 (middle column), and 0.3 (right column). Top row: the radio flux (normalized by the maximum value) where the blue and red lines represent the signal with and without collisional absorption, respectively. Middle row: the apparent radio source position (distance from the solar disk center). Bottom row: the apparent radio source area (at half-maximum level). Error bars represent one standard deviation.
