 1) Run14 D0 topological cuts re-tuning - Xiaolong Chen
For peripheral bins, suggest to also use simulation, instead of real data, to tune the cuts in order to avoid picking up fluctuations in real data. 

2) Upsilon vs. event activity from Run11 pp500 - Leszek Kosarzewski
a) check why the BBC efficiency shows a different trend compared to Bingchu's analysis
b) determine the upper limit of the last multiplicity bin for Upsilon. 100 is just an arbitrary choice.
c) check why the Upsilon efficiency increases with multiplicity.
