Ecliptic-toroidal structure of the meteoroid complex of asteroid 2003 EH1. The plot illustrates the positions of radiants in the modified ecliptical coordinate frame (λ_A, β_g) in the Hammer projection of the celestial sphere. The common ecliptic longitude, λ_g, is replaced with the angle λ_A measured from the ecliptic longitude of Earth’s apex. This apex is situated at the beginning of the frame. Abbreviations NT, ST, H, and AH stand for the northern toroidal, southern toroidal, helion, and antihelion directions, respectively (see text of Sect. 4).
