For the data sets that have already been calibrated, it would be useful to process let’s say 5-10 runs with both releases and distribute them to your run group to be analyzed as a final validation. For this processing, the suggestion is to run with default settings for CVT (i.e. the cuts mentioned above). In parallel, we will rerun the simulations that were performed with the previous tags, testing also the effect of a larger vz cut, which can be better studied in MC.</div><div class=""><br class=""></div><div class="">Let us know if you have any questions.</div><div class="">Best regards,</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>Raffaella</div></div></blockquote></div></body></html>
