The kind asked for
"coincident" when the pairs lie at one place in plan, so no turn could be found; null otherwise
The pairs fix the fit exactly (1 pair of a move, 2 of a turn and scale), so the residuals check nothing
The kind fitted: "move" while there are too few pairs to turn, or when the pairs lie at one place in plan
The alignment of the model to move: 16 numbers, column-major, mm (what SetAlignment and setModelAlignment take)
How many pairs the kind asked for still needs; 0 when it has them
Per pair, how far the moved point lands from its onto point, in mm
The uniform scale; 1 unless the kind is "turn-scale"
The turn about the vertical axis, in degrees (-180, 180]
