Hi all!

Please have a look if everything is in what you want to have in.

The new tag is named Jets_8_7_4_pre4

From the long list of release notes: - CDF/D0 Run II MidPointCone jet algorithm is bugfixed (jet algo number = 33). - Gamma+Jet correction: new corrections, new naming scheme, explicit values now in Data ORCA subsystem. - New set of values for the SinglePaticleResponse library for newer OSCAR/G4 versions. - First release of the JetCalculator class which calculates some basic jet quatities. - New jet input generator to minimize some detector effects and effects due to the typical CMS underlying event. - New jet input generator to minimize some detector effects and effects due to the typical CMS underlying event + influence of low lumi pileups. - UNDER DEVELOPMENT: New jet input generator to minimize some detector effects and effects due to the typical CMS underlying event + influence of high lumi pileups. - Small bugfix if only exact one jet is reconstructed. - New Et recombination scheme for cone like jet algorithms (proposal from Snowmass): JetRecom = 44. - All final state jets sortable also byPt. - additional Gamma+Jet corrections (incl. for UE like input types and the new MidPointConeAlgorithm) - new type of final state jet corrections: MCinfo corrections - Pileup subtraction algo to modify jet input for all algos finally included - additional set of main objects to do jet finding with enhanced functionality: PersistentJetFinder2, TransientJetAlgorithm2. WARNING: These are not able to work with actual DSTs. - new JetInputGenerators for generator input: ...NoNu, ...NoNuandSUSY and NoMuandNuandSUSY included - EcalPlusHcal input generators can be run in a tower splitted mode. - first release of the ROOT histograms based JetMET validation tool: validateRecJet.cpp, BaseJetFinder..., etc. - UNDER DEVELOPMENT: constituents for KtJets - UNDER DEVELOPMENT: 2D detector maps - energy flow class for jet input: TrackTowers uses RecTracks, RecMuons and all kind of towers splitted, unsplitted, UE curves etc. Implemented in the Persistent/TransientJet finders 2 only!

Feel free to test the improvements you requested/included.

A few things need still to be included ... see UNDER DEVELOPMENT

Cheers, Arno
