Dominant eigenvalues number versus time (h) and period common logarithm (s) representative of the MT data quality. The collected time series (having a duration of ~23 h) have been separated into shorter contiguous time windows. Subsequently, the RMEV estimator has been applied to every time window, estimating the number of dominant eigenvectors vs. period.
