Panels a and c: overall positions on the sky of radiants of theoretical filaments successfully identified with at least one real shower separated from any of considered databases. Panels b and d: radiants of meteors of individual real showers. These radiants are distinguished by various color symbols for different showers. Panels a and b: radiants are shown in the Hammer-Aitoff projection of the celestial sphere in the common equatorial coordinates. The sinusoid-like curve is the ecliptic. Panels c and d: same radiants are shown in the apex-centered ecliptical coordinates. The radiant areas are in the northern anti-helion (NAH), southern anti-helion (SAH), northern helion (NH), and southern helion (SH) cardinal directions.
