I graphed a list of rare commodities system clusters

Hello,

Hello,
I have been wondering lately about rares and decided to see if I can find other clusters like Lave/Altair/etc. So I sat down and did some calculations.
TL;DR: : There are 20 clusters which are distinctly apart.
You can find the full list of clusters, their member systems and a distance table between each centroid of each cluster in the spreadsheet
Thanks to Paul from http://eddb.io and and Maddavo from http://davek.com.au/td/

Enjoy!

Is this the 'whole' excel sheet?? Would you post that?
Thanks, o7

Sure thing:

I included a k-means calculation for attempting to cluster it between 6 and 20 clusters. I noticed that above 20, you start getting clusters with centroids that are less than 20ly apart. For me that's the threshold for 'same cluster'.
