    The centrality determination in the analysis is done using only the TMA
    (the cholm method) which has a nice correlation with the combined TMA+SiMA 
    method. There are no cuts on the number of hits in TMA in the software, so
    if this is not in the trigger we should remove this sentence from the
    paper. However, it should have no impact on the results in the paper.
    
    Cheers,
