Fig. 3From: Use of ssq rotational invariant of magnetotelluric impedances for estimating informative properties for galvanic distortionDistributions of random distortion parameters with different SDs. The normalized occurrence is the number of occurrences divided by the maximum number of occurrences at a single parameter value. Each distribution is compared with the probability density function of the theoretical normal distribution for the given SD (dashed lines)Back to article page
