Estimation errors for different orientations in all beamformers (UG, UNG, AG) and modalities (MEG, EEG, EMEG)

Angles between estimate and ground truth for 1000 random orientations per condition in V5 (A) and FEF (B) for different beamformers (UG: blue; UNG: orange; AG: yellow). Conditions differ in noise levels ($\sigma =\left[0.5,2,4\right]$) and modalities (MEG, EEG, combined EMEG). For MEG, the estimation error is evaluated in the tangential plane only. Signal strength is equal in all scenarios. Data are represented as boxplots. See also Figures S2 and S5, Tables S1 and S2.
