Table 1: Details of the observed meteor showers. Geocentric velocities $v_{\rm g}$are taken from Cook (1973). 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 1988).
