Hi Alexis,
Thanks,
so I have tried with LHAPDF6 (btw, the SysCalc makefile uses the lhapdf-config which is in the PATH, not the one which is specified via the configuration options)
I get NaNs…
Finished parsing 10000 events.
scale fact cross-section :0 nan
scale fact cross-section :1 nan
scale fact cross-section :2 nan
scale fact cross-section :3 nan
scale fact cross-section :4 nan
scale fact cross-section :5 nan
scale fact cross-section :6 nan
scale fact cross-section :7 nan
scale fact cross-section :8 nan
pdf reweighted cross-section :0 nan
pdf reweighted cross-section :1 nan
…
Cheers,
Marco
