(a) Locations of four interference sources shown with respect to the sensors. (b) Random (normalized) time courses assigned to the four interference sources. (c) Generated interference sensor data . These interference sensor data are computed by projecting the interference-source time courses in (b) through the sensor lead field obtained using the Biot-Savart law. The sensor time courses are normalized, and the ordinate indicates the normalized values.
