News from the Meteor Library: estimating meteor shower false positives

Roberto Gorelli points our attention at a recently published meteor related paper:

A generalizable method for estimating meteor shower false positives

This article has been submitted for publication in Astronomy & Astrophysics by P.M. Shober and J. Vaubaillon.

Context. The determination of meteor shower or parent body associations is inherently a statistical problem. Traditional methods, primarily the similarity discriminants, have limitations,  particularly in handling the increasing volume and complexity of meteoroid orbit data.
Aims. We aim to introduce a new, more statistically robust and generalizable method for estimating false positive detections in meteor shower identification, leveraging Kernel Density Estimation (KDE).
Methods. Utilizing a dataset of 824 fireballs observed by the European Fireball Network, we apply a multivariate Gaussian kernel within KDE and z-score data normalization. Our method analyzes the parameter space of meteoroid orbits and geocentric impact characteristics, focusing on four different similarity discriminants: D_SH, D′,D_H and D_N.
Results. The KDE methodology consistently converges towards a true established shower-associated fireball rate within the EFN dataset of 18-25% for all criteria. This indicates that the approach provides a more statistically robust estimate of the shower-associated component.
Conclusions. Our findings highlight the potential of KDE, combined with appropriate data normalization, in enhancing the accuracy and reliability of meteor shower analysis. This method addresses the existing challenges posed by traditional similarity discriminants and offers a versatile solution adaptable to varying datasets and parameters.
