Group-level coefficients of variation for center frequencies and the number of spectral peaks detected by the fooof algorithm

Calculation method	Coefficient of variation of center frequencies				Coefficient of variation of number of detected peaks
	Contralateral		Ipsilateral		Contralateral		Ipsilateral
	Mu	Beta	Mu	Beta	Mu	Beta	Mu	Beta
Across time points within the same trial	0.01 (0.004)	0.03 (0.01)	0.01 (0.004)	0.03 (0.02)	0.17 (0.06)	0.16 (0.04)	0.14 (0.04)	0.15 (0.03)
Across trials at MCR_M1 time points	0.10 (0.02)	0.25 (0.03)	0.10 (0.01)	0.25 (0.06)	0.37 (0.05)	0.41 (0.04)	0.34 (0.09)	0.42 (0.09)

Coefficients of variation were calculated per trial at each time point within ± 5 ms of MCR_M1 (top row) and across trials at MCR_M1 (bottom row).
