Conclusions

• Hit base tracks rejected by Level II trigger are less than one percent.
• Level 2 in real rejection mode is working as expected.
• The Level 2 trigger, when running in rejection mode, is cleaning up the data of the order of 30-50%.
• The mass of the nucleon in the data defined from missing mass spectra in exclusive reactions $\gamma + d \rightarrow p + \pi^- + p$ and $\gamma + d \rightarrow p + n$ is $0.936\pm 0.015$
• There is reasonable (for pass0) agreement between MC and Data in vertex and invariant mass distributions, but more analysis is needed on mean vertex dependence on kinematic variables.

Two files of Run 20111 (small fraction of g2 data) were included in this analysis. More data is needed to make final conclusions on the energy and angle dependence of the invariant mass of nucleons defined from the missing mass.
