log₁₀ t_E–log₁₀ θ_E space distribution of detectable NS lenses from the v_kick = 450 km/s simulation run (coloured) compared to that of lenses from other classes (stars, WDs, and BHs; light grey). The NS lenses are coloured by the event parameters lens velocity v_L, lens mass M_L, source distance D_L, lens distance μ_L, and a measure of background area subject to light deflection by the lens per unit time θ_E · μ_L (from top left row-wise). NSs located in the spur region distinguishable from other lens classes are nearby, have high proper motions, and are relatively very likely to cause lensing events.
