TMath::DiLog reference

ROOT

Dear all,

I am looking at the TMath::DiLog function translated here:

https://root.cern.ch/root/htmldoc/src/TMath.cxx.html#104

but I can’t find the cernlib reference to the c coefficients evaluation.
Someone has references for that specific implementation?

Best.

The original RDILOG (C332 Dilogarithm Function) “short writeup” says:

Method:
Approximation by truncated Chebyshev series and functional relations.
