Hi @bryates , may you remember me what is the goal of this issue?

Hi @bryates , may you remember me what is the goal of this issue?

I don't fully remember. We have that #REVISIT line in the plotting script. It might be related to the signal processes, either making sure their errors aren't incorrectly used, or to investigate errors for the signal. At the last US CMS meetings Nick and I talked about how even though the EFT stat errors aren't fully correct (since we don't want a quartic parameterization), it might at least be approximately correct and a better choice than 0.
