single-t: CMS_t_tch_8TeV_diff_Yt

[jacoterh]

It is not clear to me how the experimental values were obtained for this dataset, see the .yaml file here. The corresponding paper only reports the normalised distributions (figure 4) and dividing out the total cross section doesn't give agreement. Were the numbers read off from the figure directly?

The same goes for CMS_t_tch_13TeV_diff_Yt, see figure 5 here.
