[Rivet] Binning mismatch [Re: Bug in H1_2000_S4129130?]

[Eike von Seggern]

Hi Ben,

if I understand you right, you're dealing with an extra bin in the
output of rivet where there's a gap in reference data. This is because
aida cannot handle gaps in the binning properly. To fix .aida files from
rivet you can use bin/gap_removal .

Hope this helps.

Best
