Notes:
GCR electrode spacing: ARP 1 = 0.5 m, ARP 2 = 1 m, ARP 3 = 2 m, Veris 1 = 0.24 m, Veris 2 = 0.72 m; EMI mode: H = horizontal, V = vertical. Coeficients in boldface indicate
best correlations with the reference at each site and each instrument layer/mode. Depth of maximum response was approximated by the inversion software RES2DINV
