** Lifetime acceptance fitted to powerlaw
When t \textgreater{} 0.2 ps or t - t$_0$ \textgreater{} 0
\(a_{trig}(t)\), 0 otherwise.
#+begin_latex
  \begin{equation*}
     a_{trig}(t) = 1 - \frac{1}{1+(a(t-t_0))^3}
  \end{equation*}
#+end_latex

** Issues
+ Large correlation:
  #+begin_example
    PARAMETER  CORRELATION COEFFICIENTS  
          NO.  GLOBAL      1      2
           1  0.94798   1.000  0.948
           2  0.94798   0.948  1.000
  #+end_example

+ Work in progress:
  1. Trying alternate parametrisations like Error function
  2. Try binned acceptance function
