Combining triggers in Run 10 and later with the new TCU

Updated on Fri, 2011-11-04 16:06. Originally created by dunlop on 2010-01-20 16:27.

For Run 10, there is a new Trigger Control Unit, which deals with prescales independently, rather than the past methods which introduced correlations.  This changes the way that triggers need
