Description

Math tools

Mathematical tools used in the track reconstruction and data processing.

Classes

Class / file	Description
BmnKalmanFilter	Kalman filter for track propagation and fitting in the magnetic field
BmnMaterialEffects	Calculation of material effects (energy loss, multiple scattering) during the track propagation
BmnMaterialInfo	Material information (thickness, radiation length, density, etc.) at a track step
BmnGeoNavigator	Geometry navigation based on the ROOT TGeoManager: material intersections along the track
BmnMath.h	Supplementary functions: chi-square and NDF, line, circle and parabola fits of hits, Tukey weights, vertex Z by two straight tracks, progress bar
BmnMatrixMath.h	Matrix operations for the track fit (5x5 symmetric matrix inversion and multiplication)
FitWLSQ	Weighted least squares refit of tracks
BmnProfRawTools	Tools to unpack the raw data of the beam profilometer

Library

Built into the BmnBase library (see base).
