Notes.Two modifications (for two threshold values of the Southworth-Hawkins D-discriminant, Dlim) of the shower were separated from each of three databases, C, S, and E. In addition, we also give the mean elements of the orbits in the IAU MDC list as published by various authors, those by Rudawska et al. (2015) included.
