File size: 9.7 KB
Line 
1* Changes relative to V.1.8
2 - new: b-(mis)tag algorithms
3 * pt/eta dependence for b-(mis)tagging ;
4 * now also for gluon-jets
5 * related changes in the datacard:
6 deleted parameters: BTAG_b, BTAG_mistag_c, BTAG_mistag_l
7 new parameters: BTAG_func_b, BTAG_func_c, BTAG_func_g, BTAG_func_l
8 - new: Isolation: SumEt & SumPt added for muons & electrons
9 NB 'SumPt' was before 'IsolPt' in muon collection only
10 - datacard: change of several variable names!!!
11 before -> new name
12 ISOL_PT -> ISOL_trk_PT
13 ISOL_Cone -> ISOL_trk_Cone
14 ISOL_Calo_Cone -> ISOL_calo_Cone
15 ISOL_Calo_ET -> ISOL_calo_ET
16 ISOL_Calo_Grid -> ISOL_calo_Grid
17 - bug fix: EtRatio for muons
18 - new: ./configure for the installation
19 - update: default jet algorithms have change in data cards
20 - update: adding some missing "#include" statements due to a loss of
21 permissivity in recent g++ compilers.
22 - update: by default, both 1-prong and 3-prong tau jets are stored.
23 It was only 1-prong before.
24 - bug fix: bad distribution in associated number of tracks in jets
25 - vertex coordinates available in the track collection (Vx, Vy, Vz)
26 - track reconstruction efficiencies can now be floating numbers
27 - minor addition in the $(SHARED) target rule of the Makefile
28 - bug fix: the charge of the electrons in the Analysis. Electron collection
29 was the opposite of what it should have been
30 - bug fix: idem for muons in Analysis.Muon
31 - bug fix: adding some #include statements in classes in src/*, for compatibility
32 with recent versions of g++, which are less permissive than in the past

35| 16 August 2009: release Version1.8 |
36 \-----------------------------------------/
37* Changes relative to V.1.7b
38 - LHE files were not processed correctly (empty Analysis/Trigger trees).
39 Now LHEFParticle derives from TRootC::GenParticle as it should.
40 - additional data in the logfile : run date/hour + all names of used input files
41 (input event files, detector card, trigger card, beam files, particle table)
42 - bug fix: it is now possible to read "delphes root files" as an input for Delphes (GEN tree)
43 - bug fix: number of events to process is correct event if multiple files in the inputlist
44 - updates in Resolution.cpp & Resolution_ATLAS.cpp
45 - new method "invisible()" in PdgParticle, needed for invisible particles BSM
46 - new : calorimeter endcaps. DetectorCard have been updated; however, 100% backward compatible
47 - bug fix: btag was not properly working for (mis)tag efficiencies below 1%.
48 - bug fix: misplaced "#" character in the DetectorCard for ATLAS (calorimeter resolution).
49 - moving to ROOT::TRandom3 for random numbers

99
100 * Changes relative to V.1.4beta:
101 - implementation of the energy flow
102 - calotowers are first merged then smeared
103 - photons are based on these calotowers: conservative approach
104 - electrons are separately smeared according to the calotower
105 resolution.
106 - new: list of calorimeters ; CaloUtil added
107 - new: constants moved from SmearUtil.* to D_Constants.*
108 - new: GenParticle class
109 - ParticleUtil changed into D_Particle
110 - tracks and Taujets have now a charge
111 - output available as a LHCO (text) data file, in option
112 - extensive test and correction of the Bfield
113 - using now an exact computation, assuming solenoidal field
114 - about 20% faster than iterative approach

121 /-----------------------------------------\
122| 09 February 2009: release Version1.4beta |
123 \-----------------------------------------/
124
125 * Changes relative to V.1.3beta:
126 - new overal header and program output to screen.
127 - new trigger cards ATLAS and CMS-like
128 - new detector card ATLAS oriented
129 - New input parameters in the datacard for very forward detectors
130 - Modification of the Resolution.cpp code to run on the output of Delphes directly
131 - #include statements have been cleaned ; more include paths
132 in the compilation, leading to easier #include statements.
133 - extensive use of 'valgrind' for the search for memory leaks.
134 No more explicit leak is in the code. The only leaks left are
135 related to ROOT, to mcfio dependecy and to Hector.
136 This implied the systematic addition of copy-constructor,
137 operator= and correct destructors in Delphes classes
138 - update of the BField simulation; still in the case of B = Bz only
139 - JetsUtil* files renamed to JetsUtil*
140 * Private modifications in dependencies
141 - memory leaks removed in FROG (applied on Frog v1.106)
142 - systematic change of by-value parameters to "by-const-reference"
143 in Hector (applied on Hector v1.3.1)

156 - Cleaner tarball
157 * Known limitations of this release are:
158 -Work is currently being done on eta/phi variables leading to some uncertainties on these quantities when the magnetic field is switched on
