bug fix(jet Ntracks), 3-prong taus, vertex coordinates for tracks

File size: 9.0 KB
Line 
1* Changes relative to V.1.8
2 - update: default jet algorithms have change in data cards
3 - update: adding some missing "#include" statements due to a loss of
4 permissivity in recent g++ compilers.
5 - update: by default, both 1-prong and 3-prong tau jets are stored.
6 It was only 1-prong before.
7 - bug fix: bad distribution in associated number of tracks in jets
8 - vertex coordinates available in the track collection (Vx, Vy, Vz)
9 - track reconstruction efficiencies can now be floating numbers
10 - minor addition in the $(SHARED) target rule of the Makefile
11 - bug fix: the charge of the electrons in the Analysis. Electron collection
12 was the opposite of what it should have been
13 - bug fix: idem for muons in Analysis.Muon
14 - bug fix: adding some #include statements in classes in src/*, for compatibility
15 with recent versions of g++, which are less permissive than in the past

18| 16 August 2009: release Version1.8 |
19 \-----------------------------------------/
20* Changes relative to V.1.7b
21 - LHE files were not processed correctly (empty Analysis/Trigger trees).
22 Now LHEFParticle derives from TRootC::GenParticle as it should.
23 - additional data in the logfile : run date/hour + all names of used input files
24 (input event files, detector card, trigger card, beam files, particle table)
25 - bug fix: it is now possible to read "delphes root files" as an input for Delphes (GEN tree)
26 - bug fix: number of events to process is correct event if multiple files in the inputlist
27 - updates in Resolution.cpp & Resolution_ATLAS.cpp
28 - new method "invisible()" in PdgParticle, needed for invisible particles BSM
29 - new : calorimeter endcaps. DetectorCard have been updated; however, 100% backward compatible
30 - bug fix: btag was not properly working for (mis)tag efficiencies below 1%.
31 - bug fix: misplaced "#" character in the DetectorCard for ATLAS (calorimeter resolution).
32 - moving to ROOT::TRandom3 for random numbers

46 the options -Dmacos/-Dlinux/-Dwindows are automatically added
47 in CXXFLAGS when required

49 Bfield validated.
50 - new headers in each file with full references

80| 12 March 2009: release Version1.5 |
81 \-----------------------------------------/
82
83 * Changes relative to V.1.4beta:
84 - implementation of the energy flow
85 - calotowers are first merged then smeared
86 - photons are based on these calotowers: conservative approach
87 - electrons are separately smeared according to the calotower
88 resolution.
89 - new: list of calorimeters ; CaloUtil added
90 - new: constants moved from SmearUtil.* to D_Constants.*
91 - new: GenParticle class
92 - ParticleUtil changed into D_Particle
93 - tracks and Taujets have now a charge
94 - output available as a LHCO (text) data file, in option
95 - extensive test and correction of the Bfield
96 - using now an exact computation, assuming solenoidal field
97 - about 20% faster than iterative approach
98 - charged lepton isolation: IsolPt available
99 - data cards

101 - more parameters for more flexibility
102
103
104 /-----------------------------------------\
105| 09 February 2009: release Version1.4beta |
106 \-----------------------------------------/
107
108 * Changes relative to V.1.3beta:
109 - new overal header and program output to screen.
110 - new trigger cards ATLAS and CMS-like
111 - new detector card ATLAS oriented
112 - New input parameters in the datacard for very forward detectors
113 - Modification of the Resolution.cpp code to run on the output of Delphes directly
114 - #include statements have been cleaned ; more include paths
115 in the compilation, leading to easier #include statements.
116 - extensive use of 'valgrind' for the search for memory leaks.
117 No more explicit leak is in the code. The only leaks left are
118 related to ROOT, to mcfio dependecy and to Hector.
119 This implied the systematic addition of copy-constructor,
120 operator= and correct destructors in Delphes classes
121 - update of the BField simulation; still in the case of B = Bz only
122 - JetsUtil* files renamed to JetsUtil*
123 * Private modifications in dependencies
124 - memory leaks removed in FROG (applied on Frog v1.106)
125 - systematic change of by-value parameters to "by-const-reference"
126 in Hector (applied on Hector v1.3.1)
