Addition of new measurements #135

Closed dlanci closed 3 years ago

dlanci commented 3 years ago

Dear Peter,

I'm trying to add a new measurement to the list available in the measurements.yml file, namely the LHCb CMS Bs->mumu combination 2014 link

On the dedicated documentation page I couldn't find a description of the parameters that need to be passed to the measurement entry, in particular is xi the error on the best fit value for a DLL contour plot? If yes, why is it set to `xi:

Thanks, Davide

@dlanci, xi stands for x_i, where i runs from 1 to N and N is the number of parameters of the experimental likelihood (e.g. Bd->mumu and Bs->mumu are the two parameters in your case and the xi values are the coordinates in the Bd->mumu-Bs->mumu plane at which the experimental likelihood y is given). For a more detailed explanation, see the documentation discussing probability distributions in flavio and the API documentation of multivariate numerical distributions.

Thanks a lot!
