Time evolution of WD-FFP projected distance cumulative distribution function. Shown is the cumulative likelihood to find a WD-kick-ejected FFP within a given projected distance on the sky of its former host, for 1, 5, 10, and 20 Myr after FFP ejection. The dashed line highlights 10 pc in projected distance, which can serve as a benchmark to limit the search space. See also Figure 5.
