Relationship between the total velocity and the pre-impact velocity components in a geocentric Earth-fixed reference frame, as provided by the CNEOS database. Fireballs flagged as having low-D_D(D_D < 0.1) are denoted by blue squares and high-D_D(D_D > 0.1) with red circles. Fireballs with D_D < 0.008 have a yellow plus symbol. The normalized histogram for each component is stacked above the top frame of each panel. The number of bins was calculated based on Sturges’s rule (Sturges 1926).
