Rate limit at pp 500 GeV in 2013 appears to be ~1.1 GB/s, which is where the "trigger deadtime" starts to kick in as tokens aren't released fast enough.

Since the event size decreases with decreasing luminosity, and the rate of prescale=1 triggers decreases also, there is lots of room in this
bandwidth to fill in with prescaled triggers, such as JP0*DiJet and JP1*DiJet.  Below is an attempt to do this; gave 1/2 bandwidth to JP0*DiJet and JP1*DiJet
each, until JP1*DiJet hit the prescale=1 limit, at which point all remaining bandwidth goes to JP0*DiJet.  Target bandwidth was 1 GB/s, to keep safely
away from trigger deadtime.

Jeff implemented this yesterday.  Pretty close, but needs another tweak, since the underlying JP0*DiJet and JP1*DiJet cross sections decrease
with decreasing luminosity, presumably because of lower underlying event in the calorimeters.  Can also see the effect of increasing bandwidth
late in the fill in the TPC currents, since the TPC currents are approximately  A*luminosity + B*bandwidth.  First term is from amplification
of hits in the MWPC's with the gating grid closed, second term is from the readout of the actual drifting hits with the gating grid open.
Not quite keeping up, but definitely less decrease in the currents with decreasing luminosity.
