lowest-<i>pT</i> 
system is found, and gives the probability for merger with the 
second-lowest one. If not merged, it is tested with the third-lowest one, 
and so on. For the <i>m</i>'th higher system the reconnection
probability thus becomes <i>(1 - P)^(m-1) P</i>. That is, there is 
no explicit dependence on the higher <i>pT</i> scale, but implicitly 
there is via the survival probability of not already having been merged
with a lower-<i>pT</i> system. Also note that the total reconnection
probability fo
