v7_5_7

v7_5_6

v7_5_5

v7_5_4

  • Merged in branch GeomMars2018a. This brings in many Geometry changes, mostly related to the Muon beamline.
    • The default behaviour is unchanged.
    • To get the updated geometry use: Mu2eG4/geom/geom_MARS_2019.txt
    • The changes include:
      • More complete modeling of cable runs for the tracker and the calorimeter
      • Added optical fibers to the cable model
      • Added detail in the model of the cable penetrations in the IFB
      • Updated diameter of the window the IFB that allows photons to reach the MSTM
      • First version of the Hayman target; fins are not segmented but are made of a a reduced density material to give the correct mass
  • Merged offline_dev. Create phony targets such as "scons DEPS" which creates a file of subdirectory dependencies in gen/txt/deps.txt or "scons GDML" which creates gen/gdml/mu2e.gdml
  • Merged in klg_g4work - Krzysztof Genser rewrote PrimaryGeneratorAction::addG4Particle using a more general approach when (re-)creating excited ions (addressing a problem report)
  • Merge in the branch GeomMars2018a
    • This has the work done by Michael MacKenzie and Krzysztof Genser to modify the geometry for Vitaly's heat and radiation does study.
    • The only missing part is the model of the Hayman production target being prepared by Bob Bernsteing.

v7_5_3

  • Upgraded to art v3_03_01.
  • This fixes two known bugs:
    • In MT mode, for shared modules, art called begin/end Run/Subrun once per schedule.
    • SampleInput module incorrectly throws an exception when using drop commands.

v7_5_2

  • Merged in klg_g4work - added infrastructure to support separately controlling the step length in the straw gas. Also added new diagnostics related to step length in straw gas.
  • Last tag with art v3_03_00.

v7_5_1

  • Fixed the two modules that were broken in v7_5_0.
  • This is the first working tag on master that uses art v3.

v7_5_0

v7_4_2

  • This tag is on the final commit on master that builds against art v2.
  • TrkPatRec (dnb)
    • Initialized input values for ZFltLen in seed fit: that function uses those as input as well as output. This addresses

the 'uninitialized variable access' problem Pasha found using valgrind. Note that this does not affect the reconstruction output.

  • RecoDataProducts (dnb)
    • initialize the local flight length of a KalSegment to avoid an uninitialized variable read in KalSeedFit. This caused an

occasional warning message but did not affect the reconstruction output.

  • TrackAnaReco (dnb)
    • added mvaout and mvastat leaves to TrkPid and TrkQual branches
    • moved branchReset so that it didn't carry information between tracks when the same last has >1 track
  • TrkAnaReco (edmonds, DocDB-27364)
    • changed dequal leaf branch names (e.g. dequal.TrkQualDeM --> dequal.TrkQual)
    • fixed VD step bug
    • added fcl files for ensemble datasets
  • TrackPID (dnb)
    • use DeltaE (E-p) instead of E/p as a momentum-independent mu-e discriminant. Update the training.
  • TrkQual
    • added TrkQual weights file for positive tracks and set it as default in prolog for relevant TrackQuality modules
  • CompressDigiMCs (edmonds)
    • fixed bug that was causing duplicated tracker StepPointMCs
    • added a check for this to CompressDigiMCsCheck
    • added a patch module that removes duplicated StepPointMCs
    • see DocDB-20398-v17 p.3-5 for more details

  8. (brownd) Add support for production reconstruction. Update TrackAnalysisReco to include full set of analysis information.

v7_3_3

  1. 2/18/19 (rlc) Change all TTracker to Tracker. A user is most likely to be disrupted if they use personal geometry files that contain "ttracker" - these can be updated with: sed -i 's/ttracker/tracker/g' *.txt Also the names of geometry volumes change from "TTracker*" to "Tracker*".

    merge straw_conditions branch.  This creates Db and Proditions
    service, and make them required for straw reco and track fitting.
    The current default settings are still to take conditions
    from fcl, and not the database itself.


v7_3_1

            Release notes for Mu2e Offline software, v7_3_1
 
 2) Feb 6, 2019 kutscke
    First release of: Filters/src/StepPointFilter_module.cc
    This modules selects events with a minimum number of StepPointMCs
    in the named data product.
 
 1) Feb 5, 2019 kutschke
    STM sensitive detector code
      - The sensitive detector now only looks at the crystals
        rather than the crystals plus support infrastructure
      - The two crystals now have unique G4 copy numbers;
        previously they were both 0.


v7_3_0

            Release notes for Mu2e Offline software, v7_3_0
 
 1) Jan 22, 2019 brownd
     Add functionality intended to support production reconstruction.
     Fix code and scripts for calorimeter cluster time constraint in the Kalman track fit.
     Update configuration and parameters for hit error assignment in TrkPatRec

     move to art v2_12_00, adding shuffling input module

v7_2_2

            Release notes for Mu2e Offline software, v7_2_2
 
 6) Jan 22, 2019 kutschke
    Mu2eG4/geom/TransportSolenoid_v04.txt
     - Following advice from Bob Bernstein I modified:
          double pbar.coll1In.rOutRecord = 158.75
       the old value was 200.
     - This was done to avoid a conflict created when the pbar
       absorber in the PS was given a frame;  the VD's that surround
       the absorber used to overlap with the frame.
       This reduces their radius so that fit inside the frame.
 
 5) January 22, 2019, genser
 
    Enabled ShieldingM_MU2ER1, Shielding_MU2ER1, QGSP_BERT_MU2ER1 and
    their _EMZ variants as a replacement for ShieldingM, Shielding,
    QGSP_BERT physics lists plus all the customizations which were done
    in postG4InitializeTasks, to make them compatible with the MT split
    of the work between master and worker threads by inheriting from
    Geant4 reference physics lists and adding Mu2e specific calls
    encapsulated in setMu2eG4ProductionCuts and
    Mu2eG4CustomizationPhysicsConstructor.cc
    Removed obsolete physics lists. Added conditional debug printouts
    while also restructuring how the pset info is passed among functions.
    Fixed setting verbosity of tracking and stepping managers.
    setMuHadLateralDisplacement to true

    Merge in the muminus_eplus branch into master
 6) kutschke Oct 24, 2018
    Merge in Ralf's changes from branch CRV_tmp.
    These changes remove the MC awareness of the top level reco data product.
 
 5) kutschke Oct 24, 2018
    Removed unnecessary header that was creating a compile-time loop.
       BTrkData/src/TrkCaloHit.cc
       BTrkData/src/TrkStrawHit.cc
 
 4) kutschke Oct 24, 2018
    To break a compile time loop moved
        Doublet.hh and Doublet.cc from RecoDataProducts to BTrkData
 
    Modified the code base to find header file in its new location.

v7_1_4

            Release notes for Mu2e Offline software, v7_1_4
 
 3) edmonds 5 October 2018
   - add a module that separates out the "calorimeter" and "calorimeterRO" CaloShowerSteps (representing crystal and SiPM steps) out of the compression, which had combined them (Filters/src/SeparatesCaloShowerSteps_module.cc)
   - add a module that checks this separation by plotting histograms of the z-position of the steps (Filters/src/SeparatesCaloShowerStepsCheck_module.cc)
   - this is for DS-cosmic-mixing, which doesn't run the primary generation inline and so runs on the DS-cosmic primary dataset itself
   - the separated collections are not kept so that all datasets have the same output, if you run into a problem that needs the CaloShowerSteps separating, then use the new modules
 2) ehrlich 4 October 2018

      - The new comipiler is pickier about issuing warnings
        about implicit type conversions that might be lossy.
      - Inspect that it is safe to do so and make the type
        conversions explicit
      - For csv.h we had to use a pragma to disable

    - merge branch g4v10-2-p03MT, geant multi-threaded code

 10) Aug 10, 2018 brownd
    - Further consolidation and simplification of primary and mixing fcl
 9) Aug 9, 2018 edmonds
    Completed digi compression
    - StepPOintMCCollections are no longer consolidated into one and are kept separate on the output
    - SimParticleCollections, GenParticleCollections and CaloShowerStepCollections are consolidated into one output collection
      -- compressSimParticleCollection was modified to deal with this
      	-- The old behaviour is still default
 	--  To turn on the new behaviour pass in a SimParticleRemapping*
      -- SimParticles are no longer keyed to their internal ID in SimParticleCollection
    - calorimeterRO CaloShowerSteps are dropped from the event because of the Ptr bug (see DocDB-19477)
    - had to add a few modifier functions to CrvDigiMC, CaloShowerSim and CaloShowerStepRO so that I could remap their Ptrs
 
 8) Aug 2, 2018 kutschke
    Mu2eG4/src/Mu2eWorld.cc
      - After a calo geometry change from Bertrand the simulation stopped
        registering StepPointMCs in the calorimeter.
      - The reason was that the crystals in the front and back disks
        were different logical volumes with the same name.
      - Accessing the logical volumes by:
          G4LogicalVolumeStore::GetVolume(G4String const&)
        always returns the first of the two volumes with the same name.
      - So the sensitive detector handler was never registered with the
        crystals in the second disk.
      - Fixed by using an explicit loop over all logical volumes and
        checking the name to find both G4LogicalVolumes.
   The same inappropriate use of
      G4LogicalVolumeStore::GetVolume(G4String const&)
   was in place for every sensitive detector but it did not hurt us in
   other places because we did not have multiple logical volumes with the
   same name.  I fixed all of these instances.
 
 7) Aug 2, 2018 kutschke
    --ff-only merged branch trackerPatRec from Giani into MDC2018.

     Rename HitMakers to CommonMC as that is now its purpose
 4) July 19, 2018 kutschke
    EventGenerator/fcl/prolog.fcl
      Commented out the definition of PrimaryProtonGunN
      in the table EventGenerator.producers that defines the full set of
      generators.  The corresponding library is not present in this commit so it
      generates an error at job startup when running EventGenerator/fcl/prolog.fcl.
 
 3) July 18, 2018 kutschke
    Mu2eG4/fcl/g4test_03.fcl
      - Remove the individual configuration of proton time map and muon time map.
        Instead use the definitions in the prolog CommonDigiSim.  This now
        brings in the EventWindowMarker module; it's absence was the cause of the
        original error.
 
 2) July 18, 2018 brownd, bonventre
     Update straw digitization.  This includes:
     - refinements to deal with boundary conditions near the microbunch wrapping

removeStrawIndex

 This note discusses the removal of StrawIndex and it's replacement
 by StrawId everywhere.
 
 As of May 30, 2018 there is one known outstanding issue.
 I have not tested to see if the DeadStrawList correctly parses
 the lists of dead planes and dead panels.
 
 The remove of StrawIndex triggered the following additional changes:
  1) I reordered the dense array of all straws, held inside the
     TTracker object; none of our code was every supposed to
     depend on this order.  I did not find any that did.
       - old order: within a panel the straws were ordered by
                    one layer and then the other.
       - new order: straws are ordered in increasing radius
                    at their midpoint - ie alternating layers.
                    This is consistent with numbering the scheme
                    used by the tracker hardware project.
 
  2) Removed TrackerCalibrations everywhere. It is replaced
     by the many classes in TrackerConditions.
 
  3) Removed support for all variants of the tracker except
     the most recent.  I did not clean out old tracker
     geometry files - that will be another project.
     ( which will take some care because the new files are
       built as deltas to the old ones ... )
 
 In addition I cleaned up some targets of opportunity:
  4) Removed cvs history comments
  5) Removed large bodies of commented out obsolete code.
  6) Removed unnecessary includes
  7) Rewrote some loops using ranged-for syntax.
  8) Moved some files to Legacy. These make use of StrawIndex
     and I did not have the energy to convert them.
     They will be useful for people who want to ressurect their
     functionality using StrawId.  In many cases these files
     need other maintenance to keep up with other evolutions
     in our code.
 
 Thanks to Pasha for doing the work to remove StrawIndex
 and TrackerCalibrations from the CalPatRec package.
 
 Background:
 
 In the old days there were two identifiers of straws:
   DataProducts/inc/StrawIndex.hh
   DataProducts/inc/StrawId.hh
 
 StrawIndex - a dense identifier 0...(N-1)
              The order was arbitrary and no code should
              depend on the order
 
 StrawId (old style) a tuple-of-ints identifier
    originally: plane, sector( aka panel), layer, straw
    later:      plane, panel, straw
 
 StrawId (new style) a bit mapped uint16_t encoding:
         plane, panel, straw
         This is not a dense identifier but it is
         structured in a way that it convenient
         for writing FPGA code.
 
 With this change, StrawIndex is gone entirely and
 all access to straw information is via the new style
 StrawId.
 
 The key changes are:
 
  1) DataProducts/inc/StrawIndex.hh
     DataProducts/src/classes.h
     DataProducts/src/classes_def.xml
       - removed the .hh file and removed refernences to StrawIndex in the
         two genreflex files.
 
  2) GeometryService/src/TTrackerMaker.cc
      - change the order in which straws are inserted into the big array
      - Remove all use of StrawIndex
      - Lots of cleanup to remove support for obsolete trackers designs.
 
  3) TrackerGeom/inc/Straw.hh
     TrackerGeom/inc/Tracker.hh
     TrackerGeom/src/SConscript
     TrackerGeom/src/Straw.cc
     TTrackerGeom/inc/TTracker.hh
        - Remove all use of StrawIndex, which was only used as a key
          for accessors
        - Each accessor has been replaced by a matched accessor using
          a StrawId ( much of this was in place already ).
 
  4) DataProducts/src/StrawId.cc
     Reading a StrawId from a string now recognizes PlaneIds and PanelIds.
     If a, b, c are integers the formats are:
        StrawId: a_b_c
        PanelId: a_b
        PlaneId: a
     By convention a PanelId is equivalent to the StrawID for straw 0
     in that panel.  Similarly for a PlaneId - it is equivalent to the
     StrawId for straw 0 in panel 0 of that plane.
 
  5) Mu2eG4/src/StrawSD.cc
     From the G4 volume copy numbers, construct a StrawId and
     add this to the StepPointMC as it's volumeId.  Previously
     the code constructed a StrawIndex.
 
   6) Analyses/src/ConvElecHistory_module.cc
      Analyses/src/DIOElecHistory_module.cc
      Mu2eUtilities/inc/BkgElecUtilities.hh
      Mu2eUtilities/inc/ConvElecUtilities.hh
      Mu2eUtilities/src/BkgElecUtilities.cc
      Mu2eUtilities/src/ConvElecUtilities.cc
          - moved to Legacy
 
   7) Mu2eG4/inc/ConstructTTrackerTDR.hh
      Mu2eG4/inc/constructDummyTracker.hh
      Mu2eG4/src/ConstructTTrackerTDR.cc
      Mu2eG4/src/constructDummyTracker.cc
      Mu2eG4/src/constructTTrackerv3.cc
      Mu2eG4/src/constructTTrackerv3Detailed.cc
       - Removed support for obsolete tracker geometries.
 
   8) In many other files, find use of StrawIndex and
      change it to StrawId.  In most cases this was:
       a) diagnostic printout
       b) comparison to see if two objects refer to the same straw
       c) std::map<StrawIndex,T> changed to std::map<StrawId,T>
