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. The symbols used are as follows: tev as in Table 1; λ solar longitude of assumed or observed maximum of the shower activity; αg and δg equatorial coordinates of geocentric radiant; Vg and Vh geocentric and heliocentric velocity; and γ – angular distance of the mean radiant from the Sun in time corresponding to the mean longitude. The values of tev and β in the 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.
