I have rerun eta_c reconstruction for runs 926fix and 926cufix and results are the following.

Run 926fix, efficiency 27.3% (vs 25.8% for run 926 where eta_c width was considered) sigma(eta_c)=18.4 MeV (vs 31.6 MeV for run926) and sigma(phi)=3.87 MeV (without changes).

Run 926cufix with cleanup on, efficiency 19.1%, sigma(eta_c)=17.5 MeV, sigma(phi)=3.85 MeV.


So I suppose this run can be used for mixing with background.
