class JFIT::JEstimator< JLine1Z >

Linear fit of straight line parallel to z-axis to set of hits (objects with position and time).

\[ ct_j = ct_0 + (z_j - z_0) + \tan(\theta_{c}) \sqrt((x_j - x_0)^2 + (y_j - y_0)^2) \]

where:

\begin{eqnarray*} x_0 & = & \textrm{x position of track (fit parameter)} \\ y_0 & = & \textrm{y position of track (fit parameter)} \\ z_0 & = & \textrm{z position of track} \\ t_0 & = & \textrm{time of track at } z = z_0 \textrm{ (fit parameter)} \\ \\ c & = & \textrm{speed of light in vacuum} \\ \theta_{c} & = & \textrm{Cherenkov angle} \\ \end{eqnarray*}

Defining:

\begin{eqnarray*} t_j' & \equiv & ct_j / \tan(\theta_{c}) - (z_j - z_0)/\tan(\theta_{c}) \\ t_0' & \equiv & ct_0 / \tan(\theta_{c}) \\ \end{eqnarray*}

\[ \Rightarrow (t_j' - t_0')^2 = (x_j - x_0)^2 + (y_j - y_0)^2 \]

The parameters $ \{x_0, y_0, t_0\} $ are estimated in the constructor of this class based on consecutive pairs of equations by which the quadratic terms in $ x_0 $, $ y_0 $ and $ t_0 $ are eliminated.

inline

Update track parameters using updated co-variance matrix (e.g. matrix with one hit switched off).

In this, it is assumed that the changes in x and y positions are small compared to the actual distances between the track and the hits.

The template argument T refers to an iterator of a data structure which should have the following member methods:

  • double getX(); // [m]
  • double getY(); // [m]
  • double getZ(); // [m]
  • double getT(); // [ns]
Parameters
__beginbegin of data
__endend of data
Aco-variance matrix of hits
