Full Histfactory workspace in the JSON format readable by the pyhf library.
Note that the actual implementation used Poisson terms for the MC statistical uncertainties (gammas) while the pyhf format uses Gaussian terms.
This might lead to small differences and even instabilities in the fit.
One might remove the MC stat terms to increase the stability of the fit, this can be done with:

pyhf prune -t staterror likelihood_ttbar_ljets_13TeV_inclusive.json > likelihood_ttbar_ljets_13TeV_inclusive_pruned.json
