Detailed Description

template<>
class JFIT::JEstimator< JPoint4D >

Linear fit of bright point (position and time) between hits (objects with position and time).

\begin{center}\setlength{\unitlength}{0.6cm}\begin{picture}(12,7) \put( 6.0, 1.0){\circle*{0.3}} \put( 6.0, 0.0){\makebox(0,0)[b]{$(x_{0},y_{0},z_{0})$}} \multiput(6.0, 1.0)(-0.5, 0.5){10}{\qbezier(0.0,0.0)(+0.1,0.35)(-0.25,0.25)\qbezier(-0.25,0.25)(-0.6,0.15)(-0.5,0.5)} \put( 1.0, 6.0){\circle*{0.2}} \put( 1.0, 6.5){\makebox(0,0)[b]{$(x_i,y_i,z_i,t_i)$}} \multiput(6.0, 1.0)( 0.5, 0.5){10}{\qbezier(0.0,0.0)(0.35,-0.1)( 0.25,0.25)\qbezier( 0.25,0.25)(0.15, 0.6)( 0.5,0.5)} \put(11.0, 6.0){\circle*{0.2}} \put(11.0, 6.5){\makebox(0,0)[b]{$(x_j,y_j,z_j,t_j)$}} \end{picture} \end{center}

\[ t_j = t_0 + \frac{c}{n} \times \sqrt((x_j - x_0)^2 + (y_j - y_0)^2 + (z_j - z_0)^2) \]

where:

\begin{eqnarray*} x_0 & = & \textrm{x position of vertex (fit parameter)} \\ y_0 & = & \textrm{y position of vertex (fit parameter)} \\ z_0 & = & \textrm{z position of vertex (fit parameter)} \\ t_0 & = & \textrm{time at vertex (fit parameter)} \\ \\ c & = & \textrm{speed of light (in vacuum)} \\ n & = & \textrm{index of refraction corresponding to the group velocity of light} \\ \end{eqnarray*}

Defining:

\begin{eqnarray*} t_j' & \equiv & nct_j \\ t_0' & \equiv & nct_0 \\ \end{eqnarray*}

\[ \Rightarrow (t_j' - t_0')^2 = (x_j - x_0)^2 + (y_j - y_0)^2 + (z_j - z_0)^2 \]

The parameters $\{x_0, y_0, z_0, t_0\}$ are estimated in the constructor of this class based on consecutive pairs of equations by which the quadratic terms in $x_0$, $y_0$, $z_0$ and $t_0$ are eliminated.
