\tablefoottext{a}{For those objects that do not have IRAS albedo information, we have used the nominal value 0.15. $^{(b)}$ Although classified as Mars-crossers, we show in the main text that these 3 asteroids belong in fact to the Pallas family. As in the case of Phaethon, osculating orbital elements have been used.}}
