Notes. The units are in brackets following the names of the variables; D0 is the diameter at the atmospheric boundary. Ryugu/Bennu is a newly-added group that is introduced in Sect. 4.1, set to simulate the case where 2022 EB5 is a C-type meteoroid with a low density close to that of Ryugu and Bennu.
