update vp-deltachi2
Created by: RoyStegeman
@Zaharid @scarlehoff I have a question regarding the use of both the regular definition of a Hessian pdf where f=f0+error
and the '- perscription' (f=f0-error
) that was requested at the meeting of last week, as well as the request to do the mc2hessian 'on the fly' whithout storing the pdfs in a folder.
I would like to calculate the delta chi^2 distribution of both the regular mc2hessian pdf and the '- perscription' pdf. Is there a way to do this without copying the entire chain of functions and classes needed to define a pdf and calculate the delta chi2? Although I could probably do so in a less extensive way since I can be less general the vp currently is, it still seems undesirable to have the same functionality twice, especially since it won't be a small module.
P.S. at the moment this PR only includes an additional figure that was also requested, and is not related the the questions above. The added figure look like this:
