Notes. The parameters of the corresponding showers separated from the databases used as well as well-known corresponding showers found by other authors are also listed. Symbols used are as follows: tev− period of the following of orbital evolution (the theoretical stream was modeled before this time); q− perihelion distance; a− semi-major axis; e− eccentricity; ω− argument of perihelion; Ω− longitude of ascending node; i− inclination to the ecliptic; and Nsel.− the number of particles or real meteors selected from the modeled set (of 10 000 particles) or from the given database. Time tev is given in multiples of the nominal orbital period of 12P. The values of tev and β in parentheses at the orbits separated from the SonotaCo database indicate the corresponding predicted orbit, which was considered as initial in the iteration procedure within the separation.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
