Mean estimation errors for varying ${\sigma }_E$

95% confidence intervals of mean orientation estimation error for increasing noise levels in simulated EEG data for all three beamformer algorithms (UG: blue; UNG: orange; AG: yellow) and the modalities EEG (solid lines) and EMEG (dashed lines) in V5 (A) and FEF (B). The noise level in MEG data is kept constant (${\sigma }_M=4$). Signal strength is equal in all scenarios. See also Tables S3 and S4.
