Major Shower Orbital Parameters

For each of the showers detected using the wavelet enhancement method, the properties of their member meteoroid orbits are now discussed. These members are identified using the wavelet transform of the appropriate sporadic source region over the peak activity period of the shower with no speed constraints. The shower is defined as the region of positive wavelet coefficients, bounded by a delineating negative region, in the transform. The zero-boundary between these regions is never perfect—in practice the shower is here defined as the region of wavelet coefficients which occur above ~ 10% of the maximum wavelet coefficient (Wm) in the particular transform.
