\caption{\label{showers}Details of the observed meteor showers. Geocentric velocities~$v_{\rm g}$
are taken from Cook (\cite{cook}). For each shower the number of double station
meteors used for this analysis is given as well as ranges of both their photometric 
masses~$m_{\rm p}$ and maximum brightnesses~$M_{\rm max}$, average zenith 
distance of the radiant~$Z_{\rm d}$, average parameter~$K_{\rm B}$ and a meteor 
class according to this parameter (Ceplecha \cite{cepl88}).}
