DJR distribution between standalone Pythia8 and MG5

Asked by Chang Jung

Dear MG5 team,

I'm checking matching through DJR distributions.

I found in standalone pythia8, the "matching->getDJR()" distribution is different from the DJR distribution given by MG5-PY8 interface. It seems in MG5-PY8 interface, the DJR distributions is filled with "slowJet->dNext()".

May I ask the meaning of DJR distribution given by MG5?
And the difference between simply "matching->getDJR()" and "slowJet->dNext()"?

Another question is in the DJR distribution give by MG5-PY8 interface, all the distribution seems smooth.
How to check whether the matching works well or not?

Thanks a lot.
