Notes. tevol – period of the subsequent orbital evolution (the theoretical stream was modeled before this time); D.B. – database from which the observed filament counterpart was selected (F – photographic, V – video-meteor); tact – typical period of the shower activity during a year; αg and δg – equatorial coordinates of geocentric radiant; Vg and Vh – geocentric and heliocentric velocity; γ – angular distance of the mean radiant from the Sun at the time of the assumed maximum activity of the corresponding shower; A – amount of particles of the whole modeled stream that constitutes the given shower; Nsel. – the number of real meteors selected from the given database. Time tevol is given in years, the angular quantities are given in degrees, velocities in km s-1.
