Kalman References

S. Margetis | |

**Starnote-87**
D. Liko's initial implementation of DELPHI routines in STAR (Fortran)

**RK. Bock et al., "Data analysis techniques in high energy physics
experiments".** A comprehensive step-by-step book explaining all the relevant tasks for
track and vertex finding and fitting.

**R. Fruehwirth, NIM A262 (1987) 444.** A reference paper on Kalman filter techniques.
Not easy to follow for a beginner, no explicit math derivation based on examples.

**P. Billoir, Comp.Phys.Comm. 57 (1989) 390.** A comprehensive paper on Progressive
track fitting using Kalman-like fitting procedure. No "smoother". Simple and interesting.

**P. Billoir and S. Qian, NIM A311 (1992) 139.** A comprehensive paper on fast/superfast
vertex and primary track fitting using a local parametrization. Relatively easy to follow
the math.

**P. Billoir et al, NIM A241 (1985) 115.** A comprehensive paper on track matching/merging
and vertex finding using "break point" or "progressive" (pre-Kalman) techniques.

Many more to come....
