Jet clustering algorithm used in MadGraph5 at LO?

Asked by Abhik Sarkar

If I run a LO process, say p p > w+ w-, with pythia ON, delphes ON, madAnalysis OFF, the delphes .root file generated has clustered jets. What algorithm is used for the clustering processes? I couldn't find the information in the pythia card.

This wil not be part of the pythia card but rather within the Delphes one where they should have algorithm to cluster the various track in the detector.
Sorry I can not be more specific since Delphes is a complete black box for me.
