• bin: contains shell scripts to configure your system
• conf:contains an Imake template
• doc:documments
• examples/kaltest: sample programs to illustrate usage of the libraries
• src/geomlib:geometry liabrary containing classes to describe track models and measurement layers
• kallib: general purpose abstract base classes to implement Kalman filter algorithm (TVKalSystem, TVKalSite, TVKalState)
• kaltracklib: derived classes that implement pure virtuals of kallib for track fitting purpose and abstract base classes to describe a. individual measurement layers (TVMeasLayer) b. detector system as a collection of measurement layers carrying information on the material budget (TVKalDetector) c. hit point on each measurement layer (TVTrackHit)
• utils: a set of utility classes extracted from LEDA
• Makefile: makefile to build the libraries
• README: this file
• setup: script to setup environmental variables to run the sample programs

• Install ROOT if you haven't.

• cd to the examples/kaltest subdirectory.
• Choose one of the subsubdirectories in it: cdc: track fitting example for a jet-chamber-like central tracker ct: track fitting example for a simple cylindrical tracker hybrid: hybrid track fitting example for VTX+IT(Barell/Fwd/Bwd)+TPC simple: a simple line fit example using the base kallib libraries only
• cd into the subsubdirectory you chose, build the test program, and run as follows:

For hybrid:

make
cd main/prod
./EXKalTest [-b] [# events] [pt in GeV] [t0 in ns]
//Notice that without -b, you will get into event display mode.

For others:

xmkmf -a
make
cd prod
./EXKalTest [# events] [pt in GeV]
