[G12] [EXTERNAL] CLAS-g12 flux / normalization uncertainty

[Volker Crede]

Dear Colleagues,

I am currently working on the referee report for our g12 eta paper and I stumbled over the following issue. On Page 94 of our run-group note (CLAS-NOTE 2017-002), it says that we should stick to the currently quoted lower bound of the systematic uncertainty for the g12 normalization of 5.7%.

Later in Table 27, we quote a flux uncertainty of 1.7% and a normalization uncertainty of 1.8%

Can somebody clarify the situation?

1. Where does the flux uncertainty of 1.7% come from?

2. How is the flux uncertainty different from the normalization uncertainty?

3. What have others used or what will others use for these uncertainties in their papers?

Best wishes,

       Volker
