Please do not freely use these data.
Much work has gone into these data by many people (Curtis Wood, Rostislav Kouznetsov, ...).
If you wish to use the data, then please ask us.
It is likely that we could help and would want to be involved in what you do.
E.g. for scientific publications some of us would like to work with you and hence be co-author or acknowledged.
The metadata (data description) has not been fully made, because these pages are designed for our own use, and we know the metadata!
Thanks for your interest!
