Notes. Various possibilities are considered for the evolutionary phase: the pre-merger case (t0 = 12.2 Gyr), and post-mergers seen at t0 after the first passage. For each solution, we derive the angle α between the line connecting the two components and the plane of the sky, the spatial separation of the subclusters R, their separation at maximum expansion Rm and their relative velocity V.
