Table 2: 2006 encounter parameters of meteoroid trails ejected from 45P. "Maximum'' refers to the population mean for all Venus-approaching particle orbits, as described in Sect. 2. The population median is also given in parentheses where appropriate. Column 1 identifies the range of perihelion passages of the comet corresponding to each composite trail with the number of passages given in parentheses. Column 2 gives the encounter date, and Col. 3 gives the time of the trail's closest approach to Venus. Columns 4 and 5 show the duration during which the particle flux exceeds one tenth of the maximum flux (10% max.) before and after the peak respectively. Column 6 gives the orbit-to-orbit closest approach distance $\Delta $ between the trail and Venus. Column 7 gives the half-width of the trail on the B- or impact plane.
