• Landau fit on the geometrically corrected ADC distribution.

x ; G.C.ADC , y ; count

• N = ( A1 + 2 X A2 + 3 X A3 + ... ) / ( A1 + A2 + A3 + ... )

          where N  ; mean particle number,
                    Ai ; Area of ith Landau distribution,

• 1 MIP ADC = ( G.C.ADC mean ) / N

• Problem : Peak locations depend on eta.
