-Select 2 as number of parameters, give 40 as initial condition for {\tt A0} and 7 for {\tt A1}. Click {\tt Apply}. A new window should pop up with the stats of the fitting. In particular you should find a {\tt Correlation coefficient} of 0.96 and a value of $39.9756$ for {\tt A0} and $6.6529$ for {\tt A1}. These are the value of $\mu_{fit}$ and $\sigma_{fit}$ we are going to use for the SCDM method. In particular, $\mu_{SCDM} = \mu_{fit} - 3\sigma_{fit} = 20.0169$ eV and $\sigma_{SCDM} = \sigma_{fit} = 6.6529$ eV.The motivation for this specific choice of $\mu_{fit}$ and $\sigma_{fit}$ may be found in Ref.~\cite{Vitale2019Automated}, where the authors also show validation of this approach on a dataset of 200 materials.  You should now see the fitting function, as well as the projectabilities, in the graph (see Fig. \ref{fig:W_fit}-(a)).\\
