Analysis of the SonotaCo video meteoroid orbits

Since 2007 the Japanese video network provided significant amount of meteor data observed by multi station video meteor network located in Japan. The network detects meteors mostly up to +2 magnitude and is probably the most accurate and largest freely accessible video meteor database up-to-date. In this paper we present our analysis on the qualitative aspects of the meteor orbits derived from the multi station video observation and the separation of the shower meteors from the sporadic background.
