Check impact of potentially wrong ptj1 cut for ATLAS_2JET_7TEV_R06

After merging into master the agreement is gone: I used a different PDF set for the APPLgrid results. After fixing this problem I get:

This is worse than the previous comparison, but the differences are consistent with the MC uncertainties for the PineAPPL result. Another problem is that the PineAPPL results are missing a factor 2.

I'm closing this, further comparisons will be done in Issue #84.
