Selective Stimulus Parameters

Contact	Selective Pulse Width (μs)	Selective Twitch Moment (Nm)	Twitch/Tetany Scaling Factor	Estimated Selective Tetanic Moment (Nm)
Left 1	N/A^a	N/A^a	2.94	N/A^a
Left 2	255	5.86	2.22	13.01
Left 3	N/A^a	N/A^a	2.81	N/A^a
Left 4	90	3.74	3.11	11.64
Right 1	N/A^a	N/A^a	2.55	N/A^a
Right 2	255	7.33	2.35	17.23
Right 3	N/A^a	N/A^a	2.79	N/A^a
Right 4	96	5.59	2.60	14.54

The optimization produced larger selective moments when some contacts were excluded from the cost function.
