Notes. tevol – period of the following of orbital evolution (the theoretical stream was modeled before this time); D.B. – database from which the observed counterpart of the filament is selected (F – photographic, V – video-meteor); Dlim – the threshold value of the Southworth-Hawkins D-discriminant to separate the meteors of the filament or observed shower; 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. Time tevol is given in kilo-years; the angular quantities are given in degrees and velocities in kms-1.
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.
