Fig. 6

Comparison of two different calculations of the width (Δω) of the ω range allowing collisions with the Earth by projectiles on low-inclination orbits. For details, see the text. The dashed curve shows results obtained from Eq. (14), and the solid curve shows numerically calculated values using the MOID-track method.
