      Ciao a tutti,

    after Laser calibrations, according to "occhi di lince" Yiannis,
    I checked the gain of following PMTs:

            6C01-0 at 3.75 mV; 6C01-1 at 4.15 mV
            6C15-1 --> PMTs need to be checked separately (both "passerelle"
            broken today!!!!)
            6T06-0 at 4 mV; 6T06-1 at 4.4 mV
            6T07-0 one of two PMTs is flasher!!!;
            6T07-1 at 2.8 mV (undergain!!)

     A presto,

                                     Nicola
