Update Herwig JZ1 JO
Description of bug
Following up on my presentation at the PMG Jet/Photon meeting; https://indico.cern.ch/event/1156620/ I would like to request that the we recreate the Herwig7.2.1 and Herwig7.1.6 JZ1 samples with no weighting of the pT spectrum. I tested generating 50k JZ1,2 and 20k JZ3-9 events with the usual pT^4 weighting, pT^2 weighting, and no weighting. I then compared the stat error as a function of pT. It can be clearly seen in the plot that no weighting performs the best for JZ1 by a long way - lowest stat. uncertainty for the same number of generated events. For JZ2+ it could be argued that pT^2 is the best for future productions but the statistics for these slices are fine so I don't think they need to be re-made. I have attached the updated JobOptions for; 830072/mc.H7EG_jetjet_Lund_JZ1.py 830081/mc.H7EG_jetjet_Cluster_JZ1.py 830090/mc.H7EG_jetjet_Cluster_dipole_JZ1.py 830099/mc.H7EG_jetjet_72_Cluster_JZ1.py I suggest as this is effectively a bug fix with no change to the physics we use the same DSIDs.
Changes introduced
JZ1 samples with no weighting of the pT spectrum.
Tests
Produced jet pT distributions with new configuration.
