Figure 4-1 In (a) the raw data are presented in a contoured log-scale. In (b) the data were
normalised using the half space value used in the forward model. In (c) the data were normalised
as discussed above.
4.3 Decay curve analysis
The decay curve analysis is implemented in three steps.
• Decay curves analyzed for layered earth (i.e. power law) behaviour.
• Decay curves analyzed for exponential decay indicating confined conductors.
• Decay curves analyzed for sign changes not related to noise.
