Density plots of the CAMS meteors displayed in relation between the velocity components υ_x and υ_y and shown separately for all data (upper panels) and for only sporadic meteors (lower panels). All meteors of these two samples are shown in the left panels, apparent hyperbolic orbits in the middle panels, and a subset of those with hyperbolic heliocentric velocities over 61 km s⁻¹ in the right panels.
