95% confidence intervals of the orientation estimation error of 1000 randomly generated orientations for different modalities (MEG, EEG, EMEG), noise levels, beamformers (UG, UNG, AG) and targets (V5, FEF). Values are indicated in degrees. FEF: Frontal Eye Field; UG: Unit-Gain; UNG: Unit-Noise-Gain; AG: Array-Gain; MEG: Magnetoencephalography; EEG: Electroencephalography; EMEG: combined EEG and MEG; σ: Noise level.
