Notes. The showers were separated from C, S, and E catalogs. In addition, we also give the mean parameters of the related showers in the IAU MDC list as published by various authors. Further symbols are used as follows: Dmin and Dmax are the minimum and maximum values of the Southworth-Hawkins D-discriminant, characterizing the similarity of the mean orbits of the given separated real shower (or shower in the IAU MDC list) and the predicted shower of a given filament (all predicted showers are considered, therefore there is a set of the D-discriminant values); ⟨λ⊙ ⟩ is mean solar longitude; λ⊙,min and λ⊙,max are the minimum and maximum solar longitudes of shower occurrence delimiting the shower activity; ⟨α⟩ and ⟨δ⟩ are the mean equatorial coordinates of geocentric radiant; ⟨Vg⟩ and ⟨Vh⟩ are the mean geocentric and heliocentric velocities; and ⟨Dmj⟩ is the mean value of the Southworth-Hawkins D-discriminant, characterizing the dispersion of meteor orbits in a given variant (see Sect. 4.2).
