I was thinking that the plots (double ratio plots mainly) can be fit with
a P0. In this way we can quantify how constant is the double ratio.
Actually, from the P0 parameter we can also get which is the correction
factor for the data.

I agree that what to do for the 1D analysis is less clear.
However, there are large uncertainties for the enriched sample.
Perhaps for the enriched sample we can enlarge the binning such to have
smaller errors and then fit it again with a P0?

BTW, do we want to meet up this afternoon or tomorrow morning (I'm not
available tomorrow afternoon) such to finalize what to do with all the
fits?

Thanks.
