Calibration method- Position Dependence -

• Hit position dependence of the total observed energy

• Difference of position dependence in several 1/4 channels are within 2%

• 7%(edge) - 11%(corner) ?2%

• It is parameterized by simple function with hit position in 1/4 channel

  • Correction with parameterized function make hit position dependence to be flat.
    ?E/E = 0.5%
    It’s used in real data analysis
