Future prediction clouds

Purpose: shows where every currently usable statistical orbit solution predicts the object after one hour, six hours, and two days. Display: the nominal position is the cross; every variant contributes one tangent-plane point, with 50%, 90%, and 95% containment contours. Read: a compact cloud is easier to recover; a long or split cloud calls for a wider search. This is future orbit dispersion, not the past observation-residual cloud.
