I started working on the history-test project for n3fit I talked about in Varenna. In order to have this I want to have something able to compute \chi^{2} adding a covariance matrix which gives information about the PDF error. i.e.,
Where C is the normal covariance matrix and P is the one due to the PDF errors.
This is the quickest solution I could think of to get the table I wanted, i.e., the result is final, the code will not be (I just saw I left some debug code in in the commit)
Plot chi2 per replica.
There is currently an action to compute the chi2 per replica per experiment, but not a corresponding action to plot it. I will also commit an action to plot this as I am interested in having this in the reports.
