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.
