The seasonal effect is generally visible <strong>and</strong> the relative<br />
displacement are generally contained within narrow<br />
variations (the tenth part of a millimeter/half mm).<br />
Since maintenance works are being carried out where the<br />
sensors are positioned, some of the curves were modified in<br />
order to remove inconsistent data caused by accidental<br />
sensors disturbance (EF3, EF6, EF8).<br />
