Post meeting update: Trigger bias calculations have been updated and a summary is posted below as "TriggerBiasUpdate_PDF"

Anselm asked for plots of Z vs the detector eta from the simulation. Those are attached below using two different error plots (RMS and Error on Mean (EOM)). It seems pretty clear that there's no significant change in eta over the range in Z. The asymmetric detector eta cut in the analysis causes a bit of an offset in average value from zero. These plots are attached as AverageEta_zBins_*.pdf below

I've also attached the average X as a function of Z and pT. These are the AverageX_*.pdf plots below
