Hoi, I am not sure I understand the situation completely (at the moment). A further complication is that we are sitting on a moving target, since the fit and the reweighting has been changing. Anyway, the raw numbers are n04 without kaon killing oldFit 0.02118 +- 0.0027 n18 with muon killing oldFit 0.02276 +- 0.0027 n04 without kaon killing newFit 0.01895 +- 0.0023 n18 with muon killing newFit 0.01884 +- 0.0022 n25 with muon killing, repeat of n18 0.02067 +- 0.0024 n26 with muon killing, no fixed seed 0.02071 +- 0.0025 n27 with muon killing, no fixed seed 0.02136 +- 0.0025 n28 with muon killing, no fixed seed 0.02008 +- 0.0024 n29 with muon killing, no fixed seed 0.02025 +- 0.0024 n30 with muon killing, no fixed seed 0.02044 +- 0.0024 n31 with muon killing, fixed seed, with K killing 0.01900 +- 0.0071 Remember, none of the systematics jobs originally run with kaon PidKilling, that's why n04 is not the default result. The big jump we observed was in n18 (oldFit) vs. n04. Anyway, if someone feels like extracting a systematic from this, please do so and recompute the systematics table. Cheers, --U.
