    There's at least one thing I understand better. I simply forgot that the
    ADC gap was not calibrated for the TOF ADCs. When the ADC digits are
    normalized to the MIP ADC mean, the ADC gaps from tube to tube don't match
    due to different gains. That's why they are not visible in the plots I put
    on the web (all slats). So the large dE particles are in fact not so large
    (gaps converted in dE can be big).
     
    But the two band structure is still there for each slat. I tried to 
    correlate beta with dE_bot and dE_top exclusively, still the same.
    
    I'll look at it more tomorrow, it's late.
