Vera: Bi214 and Pb214  activity found by looking at electron-alpha channels

Phabrice: mention something about LTC and LEC not sure about this...
Karl:   the picture are small ..........

Victor: detector dead time and the noisy PMTs..
        Smear MC by 2% only gives 1.5% difference on the half life


generally the systematic is smaller that what they presented for Mo100 and this seem to be a problem..
