mu0 scale is not updated correctly in the operator cards.

[giacomomagni]

We have a potential problem in the function that writes the operator cards, if the Q0 scale provided in the theory card is not the same as the one defined as mu0 in the template.

In particular here:

pineko/src/pineko/evolve.py

Line 84 in f653ee2

def write_operator_card(pineappl_grid, default_card, card_path, tcard):

we should add something as:

operators_card["mu0"] = tcard["Q0"]

Thanks @toonhasenack and @Radonirinaunimi

I agree, this is an oversight.

PS: remember that in NNPDF/eko#295 we also shift $n_{f,0}$ from theory to operator

okay thanks for the reminder. That one does not require an hot fix now, right?

I feel we have been lucky here...
