Statistical metrics for the characterization of karst network geometry and topology

The authors regret that six of the statistical metrics published in Tables
2, 5, and 6 in Collon et al. (2017) are incorrect. The errors were discovered while coding and testing the open-source python package Karstnet
freely available at https://github.com/karstnet/karstnet. The errors are
smaller than 2%, except for the correlation of vertex degree, and they
do not affect the general conclusions of the paper. The corrected tables
are provided in this corrigendum, and we summarize below the
changes
