Whole process of calculation. The velocity and position in the ECI system and the initial impact energy of 2022 EB5 are first computed based on the data at the peak brightness downloaded from CNEOS. The density and the heat of ablation are set according to Table 4. The genetic algorithm is then used to search for the solution to the optimization problem and generate the final values of optimization variables. After that, the physical variables at the atmospheric boundary and heliocentric orbital elements are derived accordingly.
