\begin{columns}
\column{2in}
\begin{itemize}
\item We needed a framework that will calculate the actuall $\chi^2$, taking into account all errors collerations etc.
\item Theory predictions comes from Nazila SuperIso wrapper.
\item Used Yaml to pass the arguments.
\item Boost for mathematic operations.
\end{itemize}

\begin{frame}\frametitle{Safety matters}
\begin{itemize}
\item This cards style I addopted from HFAG.
\item Additionally code check if the correlation matrix makes sense~$\rightarrow$ symmetric.
\item Claculates the total $\chi^2$ and returns.
\item In principle we will have assymetric errors. The treatmend of the standard:
\end{itemize}
\begin{equation}
\chi^2 = \Delta^T V^{-1} \Delta
\end{equation}
\begin{itemize}
\item We will have four covariance matrix: $V_{++}$, $V_{-+}$, $V_{+-}$, $V_{--}$.
\end{itemize}
\end{frame}

\begin{frame}\frametitle{What is missing?}
\begin{itemize}
\item We do not have theory errors in. 
\item Started discusion with Nazila about them.
\item This is tricky, we need to properly recalculate the errors from SM values.
\item Limit treatment procedure. We had some discussion about this but we should make a decision here.
\item My personal view: procedure should be as unbias as possible.

\end{itemize}
