MEG artefacts: tram traction power

Published:

more MEG artefacts: the tram runs in ~200 meter distance from the MEG lab here. even though the MEG sensors are shielded by a few tons of metal, they still pick up the railway traction power signal (at 16.67 Hz in Germany), a demo of their high sensitivity.
