</div>At some level it doesn't matter much since the absolute energy<br>
calibration of the pion-rejector (ie. from momentum setting to momentum<br>
setting) isn't important. It would be nice to make some sense of it<br>
though...<br>

Do the Transversity guys see the same trend in their analysis?<br>
