Table 1. Comparison of the Three Alignment Media Used in This Work^a.

	NSPE	correlation	SD (Hz)	Q-factor
Pf1-e vs Pf1-s	–0.32	0.45	11.2	1.375
Pf1-e vs DHCP/DMCP	0.3	0.31	15.67	1.219
Pf1-s vs DHCP/DMCP	–0.54	0.86	8.62	0.533

^aThree alignment media: two steric (DMPC/DHPC and Pf1 at high ionic strength, Pf1-s) and an electrostatic (Pf1 at low ionic strength, Pf1-e).
