H/V curves at the five arrays with increasing aperture: KUM_SS1 (a), KUM_S (b), KUM_SM (c), KUM_M (d) and KUM_LL (e). The average H/V curves at the seven stations (solid curves, in left panels), their mean curve with standard deviation (solid and dashed lines in middle panels), and array geometry (open circles in right panels) are also shown. The comparison between the average H/V curve (solid line) and the average fundamental Rayleigh wave ellipticity curve (dashed line) obtained by Raydec analysis (Hobiger et al. 2009) for station #7 of the KUM_S array is also shown (f)
