* Selecting "All" for the Hist Group shows page and frame numbers for the histograms in QA PostScript files.
* The example histograms shown are for minimum bias real data, with mid-multiplicity range histograms shown for those separated by multiplicity. There may be differences between these histograms and those for other multiplicity ranges, with different triggers (e.g. central trigger), or for simulated data.
* For real data, the z-axis location of the primary vertex varies considerably, from event-to-event, and the distribution changes considerable from file-to-file. Please consider this when looking at z-related (e.g. dip angle, tanl) distributions.
