Using an alternate Jet Finder

The whole sequence can be redone with and alternate jet finder. We used '!FastJet' and we replaced the Durham algorithm with KT. For this, we changed Durham_4Jets to Kt_4Jets and used

<processor name="MyFastJetProcessor4" type="FastJetProcessor">
       <parameter name="algorithm" type="StringVec"> kt_algorithm 1.0 </parameter>
       <parameter name="clusteringMode" type="StringVec"> ExclusiveNJets 4 </parameter>
       <parameter name="jetOut" type="string" lcioOutType="ReconstructedParticle"> Kt_4Jets </parameter>
       <parameter name="recParticleIn" type="string" lcioInType="ReconstructedParticle"> LooseSelectedPandoraPFANewPFOs </parameter>
       <parameter name="recombinationScheme" type="string">E_scheme </parameter>
       <parameter name="recParticleOut" type="string" lcioOutType="ReconstructedParticle"> LooseSelectedPandoraPFOsInKt_4Jets </parameter>
</processor>
The relevant scripts and XML templates are here. The outputs are stored in /afs/phas.gla.ac.uk/data/ilc/datasets01/1.4tev/ZVRES_out/ and have the prefix kt added the file name.
