Table 1. Dot product between the observed motions and the Normal Modes of C2 (3DKX), C3 (3DKY), and C6B (model) forms of RepB.

	*C2	*C3	*C6B
C2	—	0.19/0.49/0.51	0.59/0.60/0.72
C3	0.23/0.52/0.63	—	0.19/0.52/0.61
C6B	0.63/0.64/0.64	0.02/0.35/0.39	—

The numbers correspond to the dot product obtained when the essential space is defined by 2, 5 or 10 eigenvectors (dot2/dot5/dot10) as explained in the Methods section. Dot products expected by chance are 0.00055, 0.0014 and 0.0028 for 2, 5 and 10 eigenvectors respectively.
