In the original publication [1], there was a mistake in Table A3 (in Appendix B) as published. The error in question is one numerical typo in the first row of numerical results, the value 129.3 should be 1329.3. The corrected Table A3 appears below. The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.
Appendix B
