Detailed Description

=== This is the base class for the linearised chi-squared track fit algorithms.

=== This is the base class for all the track fit algorithms

=== Create requested track fitter

=== This is the simple linear regression with 4 helix parameters (qOverPt, phiT, z0, tanLambda) track fit algorithm.

=== Written by: Sioni Summers and Alexander D. Morton.

Kill duplicate fitted tracks.

Currently this is intended to run only on tracks found within a single (eta,phi) sector.

=== Represents helix state & last associated stub. === All variable names & equations come from Fruhwirth KF paper === http://dx.doi.org/10.1016/0168-9002%2887%2990887-4

=== This is the base class for the Kalman Combinatorial Filter track fit algorithm. === All variable names & equations come from Fruhwirth KF paper === http://dx.doi.org/10.1016/0168-9002%2887%2990887-4

=== This is the Kalman Combinatorial Filter for 4 & 5 helix parameters track fit algorithm.

=== All variable names & equations come from Fruhwirth KF paper

=== http://dx.doi.org/10.1016/0168-9002%2887%2990887-4

=== Summary of variables: === m = hit position (phi,z) === V = hit position 2x2 covariance matrix in (phi,z). === x = helix params === C = helix params 4x4 covariance matrix === r = residuals === H = 2x4 derivative matrix (expected stub position w.r.t. helix params) === K = KF gain 2x2 matrix === x' & C': Updated values of x & C after KF iteration

=== Boring: F = unit matrix; pxcov = C

=== Summary of equations: === S = H*C (2x4 matrix); St = Transpose S === R = V + H*C*Ht (KF paper) = V + H*St (used here at simpler): 2x2 matrix === Rinv = Inverse R === K = St * Rinv : 2x2 Kalman gain matrix * det(R) === r = m - H*x === x' = x + K*r === C' = C - K*H*C (KF paper) = C - K*S (used here as simpler) === delta(chi2) = r(transpose) * Rinv * r : Increase in chi2 from new stub added during iteration.

Multiplex the tracks found by several HT onto a single output optical link. (where throughout this class, the word "link" corresponds to a pair of links in the hardware). so that tracks that can't be sent down the link within the time-multiplexed period are killed.

This class replaces the 2D track collection in the r-phi HTs with the subset of the tracks that can be output within the TM period.

If you wish to change the multiplexing algorithm, then edit this class ...
