Positions of predicted radiants in the constructed models (panels a and b) and radiants of corresponding real meteors (panels c and d). The positions are shown in the equatorial (panels a and c) and the Earth apex centered ecliptical coordinate (panels b and d) frames. Panels a and c: the sinusoid-like curve is the ecliptic. The positions of the radiants of various filaments and showers are distinguished by various symbols and colors. Panels c and d: positions of meteor radiants separated from the C, S, and E catalogs are also distinguished by black, blue, and yellow, respectively.
