Density representation of the Kresáks’ diagram for databases of (a) FRIPON, (b) GMN, (c) EFN, (d) Ondřejov, (e) CNEOS, and (f) CAMS, given in logarithmic greyscale. The red curve plots the parabolic limit, and the red crosses represent hyperbolic events that overpass such limit with a p value lower than 0.14% (3σ). Each panel also displays the percentage of hyperbolic (black) and 3σ hyperbolic (red) events.
