- Commissioning Efforts

- Layer efficiencies (Ahmed)
- Up/down gain ratios for spring data (Mark)
- Muon decays (Will)
- Michel Spectrum
- Michel Reconstruction issue (Will M)
- Electron spectrum puzzling as it is about half of what is expected. It also does not peak at the 53 MeV
- Andrei: Suggested that we might be simply plotting minimum ionizing spectra, but unclear why all the electron energy is not reflected there.
- Reconstruction
- Eta reconstruction (Tegan)
- Single-ended energy summary (Will M)
- Summary of including single-ended hits into the energy distribution. The effect is to increase the mass by 4 MeV and reduce the width by 0.2-0.4 MeV.
- The data base updated will wait till the new atten and up/down gain ratios can also be included.
- Simulations
- CPPsim (Tegan)
- Cosmics runs & simulations with B-field on (Andrei)
