The publication of this article unfortunately contained mistakes.

• 1. One affiliation was missing for the author Oscar F. Mojica: 4 National Institute of Science and Technology of Petroleum Geophysics (INCT-GP/CNPQ). Instituto de Geociências, Universidade Federal da Bahia Campus Universitário da Federação, Salvador, BA 40170–115, Brazil.

• 2. There was a mistake in equation 3. The correct equation is:

  $$\begin{aligned} \Phi _a= \frac{{||log(\mathbf{d}^{\mathrm{cal}}(\mathbf{m})) - log(\mathbf{d}^{\mathrm{obs}}(\mathbf{m}))||}_{2}^2}{N_{\mathrm{obs}}}. \end{aligned}$$

• 3. The citation of figures 16 and 17 was exchanged in the text.

The original article has been corrected.
