    * Array to convert hdc/adc to the real Photomultiplier

    * Each single row is a sequence of photomultipliers in this shape
    * - The elements from  0 to  7  correspond to S11_1->S11_8
    * - The elements from  8 to 13  correspond to S12_1->S12_6
    * - The elements from 14 to 15  correspond to S21_1->S21_2
    * - The elements from 16 to 17  correspond to S22_1->S22_2
    * - The elements from 18 to 20  correspond to S31_1->S31_3
    * - The elements from 21 to 23  correspond to S32_1->S32_3
    * 
    * Example: 
    * -------> the tdc of the S12_3B photomultiplier correspond to tdc[(tof[2][10])][(tof[3][10])] 
    * -------> the tdc of the S31_3A photomultiplier correspond to tdc[(tof[0][20])][(tof[1][20])]
