Total impact energy provided by CNEOS as a function fireball year. Hyperbolic and calibrated (with independently determined orbits from ground-based observations) events are indicated with diamonds and crosses, respectively. The color of calibrated event markers corresponds to the D_D value between CNEOS-derived and ground-based orbits. Selected D_D thresholds are indicated by a dotted line on the colorbar, delimiting each sub-colormap segment. The gray area highlights the parameter space that results in high-D_D orbits for the calibrated events (based on the criteria D_D < 0.1). Two vertical and two horizontal dashed lines define the possible boundaries of the high-D_D orbit region. 2008 TC3 has been sign-corrected following Peña-Asensio et al. (2022).
