Chi squared under four scenarios -- using 10, 15, and 20 GeV H-matrices, and interpolating

Efficency under the same four scenarios -- vertical axis is pi0 efficiency; horizontal is photon efficiency

Photon energy deposition fraction in each tile around a central tile.

All photons (and pi0's) in this study were fired at a corner where four tiles meet. The central "tile" is actually the tower of tiles with the same theta and phi components which has the most energy. For each cluster, a matrix is made of the central tile and its eight neighbors. This matrix is the flipped vertically and horizontally and transposed until the following conditions are met:

• The largest (most energetic) tile is the central tile
• The left column is larger than the right column
• The top row is larger than the bottom row
• The left column is larger than the top row
