    After aligning the pedestal, I set the software gain in order to align the single photo-electron peaks at channel 150.
    Figure 1 shows the fit of the single photo-electorn peak.
    Figure 2 is the sum of all the mirrors after calibration.

    --------------------------------------------------------
    Number of photo-electron per mirror:

    #1 8.3
    #2 7.6
    #3 7.2
    #4 9.3
    #5 5.5
    #6 9.3
    #7 6.7
    #8 10.0
    #9 9.7
    #10 9.6
    -------------------------------------------------

    ADC #5 has a too low number of photo-electrons.
