Following the spin meeting I followed up on the questions

->How many events get dropped due to the requirement of having a pi0 candidate?

A: running over 10k events, no event got rejected

->are photons excluded with a track pointing to them?

(I think this question was aimed at the fact, that there is a high probability that a track will lead to a point in the emcal, so by not excluding these points, the probability that the event is kept is more likely)

A: No, and given the answer to the previous question it looks like there will be no problem with dropped events.

---> There was also a *bug* in the presentation: I mistakenly didn't add the xF cut to the p_t plots in the code, so here I add the missing plots. You can imagine a trend in p_t

x-axis: p_t[GeV], The plotsare for xF>0.01, xF>0.015, xF>0.03using fits and as a comparison for xF > 0.03 using L/R asymmetries

And here are the results for the xF binning with the sin fit. You can see that the results are similar to the L/R asymmetries. Actually the asymmetries are larger, but the error bars are also slightly greater.

Overall this gives confidence in the results.
