@kamillaurent, @jekoorn, This is the branch that could be used to compute the aN3LO DIS coefficient functions that reproduce the 4.0 predictions. The idea would be to recompute the theories with 4.1 settings but using the 4.0 methodology for the N3LO approximation.

But perhaps before recomputing the theories, let's wait for the Code Meeting this afternoon for the proper action plan.

thanks! I agree re code meeting.

Which version of yadism should I use for 4.0 methodology?

I don't remember on top of my head the exact released version but this branch has been explicitly checked to reproduce exactly 4.0.

Do we want to use the 4.1 theory with PTO set to 3? Or the new cards that we are working on in NNPDF/nnpdf#2494?

On a separate issue, ...

EDIT: let's do it #387 🙃
