Meteoroid orbits from video meteors. The case of the Geminid stream
Original language description
The observed orbital dispersions in the Geminid stream described by the median absolute deviation range from 0.029 to 0.042 AU(-1) for the video catalogues. The distribution of the semi-major axes of video meteors in all the databases, except for the Ondrejov (Czech) data, seem to be systematically biased in comparison with the photographic and radio meteors. The determined velocities of the video data are underestimated, probably as a consequence of the methods used for the positional and velocity measurements. The largest shift is observed in the EDMOND and SonotaCo catalogues. Except for the measurement errors which influence the analyses and their interpretations, we also point out the problem of the uncertainties of the numerical integration procedures that influence the simulations' results. Several experimental integrations of the Geminids parent asteroid, which we performed from the present to the past and then back to the year 2015, showed that a complete reproduction, including also the mean anomaly, is only possible for a time span of about 2700 years.
