Scientific paper
Radar meteor observations from Ondrejov, Czechoslovakia, and from Ottawa, Canada, have been used to determine the number of density of meteoroids through the cross section of the Geminid meteor stream. Cross sections are calculated for a number of classes of echo duration (particle size) to a resolution of one hour of earth motion. The position of the peak in the stream profiles shifts by - 0.1 deg/meteor magnitude. The widths of the stream profiles and the degree of asymmetry are also dependent on particle size.
