CMS_TTB_DIFF_13TEV_2016_2L_TTMNORM C-factor error

Created by: J-M-Moore

Currently, it is not possible to run a fit using CMS_TTB_DIFF_13TEV_2016_2L_TTMNORM with the QCD C-factor. The length of the dataset is 6, whilst the length of the C-factor is 7.

In [6]: len(cfdata.central_value)
Out[6]: 7

In [7]: ndata
Out[7]: 6

I guess this is possibly because this set is a normalised distribution, so a cut needs to be applied so that all points remain independent. Perhaps the cut has been directly included when the FK-tables were generated, rather than included in filters.yaml?

If this is the case, a quick fix is to remove one value from the C-factor files. But the question is... which one?
