In the end, we're solving all these structures because we believe (or at least hope) that they'll be useful for understanding biology. That means that biologists should be able to understand what we deposit. When I've tried to teach undergraduates "what to make of" structural models, I find I can give (most of) them an intuitive feel for what B tells or doesn't tell them. I don't have time to even bring up TLS parameters. The file that gets downloaded from the databank and displayed by pymol or PDBviewer needs to be as simple as possible while still being true. Exactly how those Bs were derived should be included in the file, but in a way that the non-specialist users can get by without reading it all (since they most certainly won't ;-) ).

I believe the simplest and most honest thing to deposit are the parameters of your model,
viz the TLS parameters and the residual B factors.
Derived quantities should be calculated as and when you need them.

RNA is really nifty
DNA is over fifty
We have put them
  both in one book
Please do take a
  really good look
