Hi all,

The updated numbers for the transparency are in Tab: Summary of the Final spreadsheet.

Assuming I am using the right tracking efficiency, this is where we are at:
Hydrogen:
Q2=8, 1.00+/-0.01
Q2=9.5, 0.98+/-0.02
Q2=11.5, 1.01+/-0.03
Q2=14.3, 0.97+/-0.03

Carbon:
Q2=8, 0.571+0.008
Q2=9.5, 0.522+/-0.011
Q2=11.5, 0.561+/-0.16
Q2=14.3, 0.521+/-0.019

I’m sort of confused why the Q2=9.5 and 14.3 are so low for carbon. It’s interesting to see that for hydrogen these two are also lower (although within uncertainty so maybe nothing).
