Fig. 6


Distribution of geocentric radiants of modeled particles, which approach the Earth’s orbit within 0.05 au at the present in the ecliptical coordinate frame with the modified ecliptic longitude to place the Earth’s apex into the coordinate origin. This distribution was derived from the model for tev = 500 Po and the strength of the P-R drag characterized with value of parameter β = 0. The radiant positions are shown in the Hammer projection of celestial sphere. The mean radiants of filaments F1 and F4 as well as F2 and F3 are connected (light blue dashed lines) to show the symmetry of the radiant areas.
