Saving (slightly modified) notes obtained from the author of the code of the upstream code:
The code has a faithful implementation of D3-zero and D3-BJ. There are also some optional parts (lines 331 to 341) that will selectively ignore or scale certain interatomic terms. Without these lines our ‘scalefactor’ is set to 1, which is equivalent to standard D3 terms.
The pars.py file contains the up-to-date functional damping parameters (lists zero_parms & bj_parms) as of about 1.5 years ago.

We can turn this then into documentation.
