Positions of radiants of theoretical particles (plot a)) of filament F1 and those of real meteors of the corresponding shower b). The meteors were separated from the CAMS (blue asterisks for D_lim = 0.17 and red crosses for D_lim = 0.07) video database. The shown theoretical radiants were obtained in the models for β = 0.00001 and t_ev = 5, 10, 20, 40, and 80 kyr. The positions for the different t_ev are distinguished using the different marks and colors. The coordinate frame is equatorial.
