| riemannFit::HelixFit | brokenline::helixFit (const riemannFit::Matrix3xNd< n > &hits, const Eigen::Matrix< float, 6, 4 > &hits_ge, const double bField) |
| | Helix fit by three step: -fast pre-fit (see Fast_fit() for further info);
-circle fit of the hits projected in the transverse plane by Broken Line algorithm (see BL_Circle_fit() for further info);
-line fit of the hits projected on the (pre-fitted) cilinder surface by Broken Line algorithm (see BL_Line_fit() for further info);
Points must be passed ordered (from inner to outer layer). More...

| __host__ __device__ void | brokenline::translateKarimaki (karimaki_circle_fit &circle, double x0, double y0, riemannFit::Matrix3d &jacobian) |
| | Changes the Karimäki parameters (and consequently their covariance matrix) under a translation of the coordinate system, such that the old origin has coordinates (x0,y0) in the new coordinate system. The formulas are taken from Karimäki V., 1990, Effective circle fitting for particle trajectories, Nucl. Instr. and Meth. A305 (1991) 187. More...
