Predicted electron cutoff momenta as function of emission angle, pc(θf), for n=0, 1, 2 recollisions at optimal CEP for upward emission; is the free space quiver momentum. Small/large circular symbols denote the critical birth/emission angles associated with respective highest cutoff momenta (see inset for corresponding radial trajectories); blue/red filled circles show critical emission angles and cutoff momenta from experiment and M3C simulations; shaded rings are guides to the eye.
