Table 1 Values of SNR and API for jitterless data with N = 3, for various fixed values of λ , as well as for the varying-lambda strategy detailed in the text

From: Separation of phase-locked sources in pseudo-real MEG data

	λ	0.025	0.05	0.1	0.2	0.4
SNR	Fixed	17.5 ± 21.2	27.5 ± 18.0	34.4 ± 4.3	27.2 ± 3.6	13.5 ± 5.5
	Varying			48.9 ± 8.7
API	Fixed	0.795 ± 0.570	0.369 ± 0465	0.048 ± 0.057	0.079 ± 0.027	0.327 ± 0.097
	Varying			0.013 ± 0.015

While the best fixed value, λ = 0.1, yields decent results, the results using a varying value of λ are consistently better, with a large margin.
