\caption{\label{trails}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.}
