Problem
A research group fits a single equivalent dipole to a patient's combined ECG and MEG recordings and obtains an excellent fit (residual error under 2%). They report: “This proves that the abnormal electrical activity originates from a single point source at the fitted location; no other current distribution could account for these measurements.” Find the error in this claim.
