Logic for avoiding L1 trigger bias

We want to measure the efficiency for an offline jet to be matched to a L1.5 jet. For W+jet events, we need to avoid trigger bias at L1. To do this, we need to require that something other than our jet fires the tau piece of the L1 trigger. Here is one way we could do this.

def atLeastOneTag(jets):
    for jet in jets:
        if matchedL1(jet):
            return True
    return False

def matchedL1(jet):
    < trigger matching voodoo >

for probejet in selectedjets:
    otherjets = copy(selectedjets)
    otherjets.remove(probejet)
    if atLeastOneTag(otherjets):
        # you now have unbiased probe jet!
        histogram.Fill(probejet.pt)
