Reports

Comparison of angle resolutions by using two different descriptions of Hampton (Tohoku) and Kyoto
Introduction to Suzuki's and Itabashi's talks

Matrices that were involved four peaks of Al were used as initial matrices for the latest tuning (Hampton)
→
Geant4 Simulation (HRS)
- Momentum resolution with the point particle generation will be evaluated (Suzuki (Kyoto)).

Tuning test with Al peaks.
- Information about the matrix tuning and matrices (which have not been involved Al tuning at all)
  will be provided to Japanese group (→ Hampton)
  → It was found that the initial matrices that were used for the latest tuning were tuned matrices involved by four of Al peaks.
  → ~~Japanese group will test how the momentum tuning works.~~
- Test of single peak inclusion of the Al data for the tuning
  → any other peaks grow? (→ Tohoku/Kyoto)
Angle resolution. Definition of the angle needs to be checked at first (→ Hampton/Tohoku/Kyoto).
How was the QF shape obtained in Bishnu's spectrum?
→ We want to see some typical figures by which the analysis procedure can be discussed quantitatively.
H contamination
→ Shape of Λ may be better to be asymmetry to discuss about the Σ bound region. (→ Hampton)
