Distribution of αᵕβ values for JFC-like fireballs from the DFN, MORP, and FRIPON observation networks. Here, γ is the trajectory slope relative to the horizontal. If a macroscopic event is considered to have a final mass of ≥50 g, assuming ρ_m = [2240,3500] kg m⁻³ (carbonaceous and ordinary chondrite, respectively) and c_dΛ = 1.5, meteorite-dropping events can easily be identified given the range of possible shape change coefficients (µ). The black lines correspond to the ordinary chondrite density, whereas the red lines denote a carbonaceous meteorite density, described by Eqs. (3)–(6). The coloration is indicative of the percentage of particle clones within the 10 kyr simulations that reached perihelion values >2.5au, and only fireballs that also fulfilled the meteorite-dropping criteria of V_final < 10 km s⁻¹ and H_final < 35 km are considered likely meteorite droppers (after Brown et al. 2013).
