Fig. 12From: Validity of the dispersion relations in magnetotellurics. Part II: synthetic and field dataMaps of maximum absolute DR-II violation within the period range from 10−3 s to 103 s for various MT functions. Green dot marks out the location of the reference site used for calculation of the inter-site tensors \(\hat{M}\), \(\hat{Q}\) and \(\hat{S}\); red dots show the MT sites to be considered separately (see Figs. 13, 14)Back to article page
