We can improve the computation of the necessary couplings for PineAPPL here

pineko/src/pineko/evolve.py

Lines 181 to 188 in 63af934

sc = eko.couplings.Couplings(
tcard.couplings,
tcard.order,
evmod,
quark_masses,
hqm_scheme=tcard.quark_masses_scheme,
thresholds_ratios=np.power(list(iter(tcard.matching)), 2.0),
)

by

  • using the physical masses, i.e. if we want MSbar masses actually use them
  • determine the $n_f$ of the central and pass that as nf_to

I think we should address this asap and easily, especially:

determine the $n_f$ of the central and pass that as nf_to
