 note = {We have employed the new line detection method and successfully separated the tworadiant points that correspond to the dust trails of Comet 55P/Tempel-Tuttle's perihelion passagesin 1699 and 1866. This method integrates pixel values of a CCD image along a line direction, whichenables us to detect 30 times fainter meteors than usual detection methods. It can also determinethe angle of the line direction precisely. Radiant points of 2001 Leonids derived by this methodwere found to be consistent with those predicted by McNaught and Asher., 資料番号: SA4638960000},
