Column names in diversity data (downloads) not documented in the API #62
The names X_Ft, X_bL, X_FL, X_bt should be in the API documentation under "value"?
I cannot find these names anywhere in the PBDB documentation; it would help students/new users.
Thanks! I knew this from the paper but I was writing an exercise for undergrads to make some calculations by hand and read the API definitions to understand differences between fields and generally the nature of the data. But they pointed out this wasn't there. I think it would be nice to add these field and a citation of the paper, undergrads can't be expected to know it.

Emilia,
I can't speak for the incompleteness of the documentation, but I believe those are the diversity classes for boundary crossers from Foote (2000):
https://geosci.uchicago.edu/~foote/REPRINTS/DeepTime.pdf
i.e. X_Ft is the number of taxa that first occur in that interval but have a last occurrence beyond the end of that interval.
Cheers,
