> Did you use https://raw.githubusercontent.com/johncarlosbaez/el-nino/master/R/average-link-strength-1948-2013.txt at all ? I am wondering if that data is the same in your work, Ludescher and my analyses.

I wrote the R script that generated that data (and made a shorter set of data myself). It is similar to, but not identical to Ludescher et al's link strength. See John's [Blog post](http://johncarlosbaez.wordpress.com/2014/07/08/el-nino-project-part-4/)
