a Geoelectrical dimensionality maps obtained from the WALDIM code (v1.1) averaged over five period bands for the La Torrecilla survey. Black arrows indicate the strike direction where the structure is 2D or 3D/2D and their size is inversely proportional to its error. b Phase tensor ellipses for each site and period. The color of the ellipses represents the value of the skew angle
