On the man-made contamination on ULF measurements: evidence for disturbances related to an electrified DC railway
An analysis of measurements performed at L'Aquila (Italy) during a deep minimum of solar and magnetospheric activity (2008–2010) allowed for the evaluation of possible contamination of the ultralow-frequency (ULF) spectrum (<i>f</i> ≈ 1–500 mHz) from artificial distur...
