Detailed Description

Linear Fit Rp and t0 to pixel times for given chi0

Regarding the formula for pixel times

\[ t_i = t_0 + R_p / c * \tan ((\chi_i - \chi_0) / 2) \]

as a linear expression f(tan_i) determine $R_p$ and $t_0$ by linear regression.

For every set of t_i (every eye in an event) a new object is needed.
