 Software for automated data analysis of Wilson_tm fermions with GEVP techniques.
+
 The GEVP is solved as outlined in 1010.0202, i.e., given a correlator f(t) the following matrix is constructed:
 
 ```math
-SE = \frac{\sigma}{\sqrt{n}}
+C(t) = \begin{matrix} f(t) & f(t+\tau) \\ f(t+\tau) & f(t+2\tau)  \end{matrix}
 ```
 
 To run the code in the juliaREPL type:

 rwf set to true if you want to include reweighting factors
 compute_t0 set to true if you want to extract t0 from ms.dat file. Otherwise, t0 is taken from 1608.08900 in const.jl
