    keyword=Bad linear fanout for DE:13-16

    Miha found that the linear fanout for DE: 13-16 had fluctuating ripple on the end of the tail of the outgoing pulse. This caused the discriminator to make several pulses from this ripple... several hits for each incoming pulse.

    We'll need to see if this effected the e04007 data, as well. This would have showed up as higher rate in the scalers for those channels, and may have effected the DE trigger.... should not have impacted the number of hits for the individual DE PMTs, but may have shifted the DE trigger by 10-20 ns depending on the deadtime or prescale set for the DE trigger.
