As part of the validation work, samples of MC Sidis events and data have been processed and are available for physics analysis. </div><div class=""><br class=""></div><div class="">Specifically, the available samples are:</div><div class=""><br class=""></div><div class="">- <b class="">5 M Sidis events on proton in RG-B Spring19 configuration</b> (no background). Files are available at:</div><div class="">• /volatile/clas12/users/devita/cvt/simulations/protonSidis_bs0: no beam spot information used<br class="">• /volatile/clas12/users/devita/cvt/simulations/protonSidis_bs1: beam spot used in the track-finding <br class="">• /volatile/clas12/users/devita/cvt/simulations/protonSidis_bs2: beam spot used in track finding and Kalman Filter<br class=""><div>As discussed in the meeting today, using the beam spot constraint will improve the resolution for tracks originating from the primary vertex but it will affect tracks originating from detached vertices. We ask therefore your feedback on comparison of these samples to quantify the impact on physics analyses and define the best strategy for pass2.</div><div><br class=""></div><div>- <b class="">Data samples from RG-B and RG-A Spring 19 </b>processed with beam spot constraint on track-finding only<b class="">,</b> in /volatile/clas12/users/clas12/cvt/ccdb_2022-01-02-6342-devbs8/dstcvt</div><div>These include:</div><div>• RG-B Spring19 Low luminosity runs 6371, 6373, 6374 (10.6 GeV, 5 nA) </div><div>• RG-B Spring19 Production run 6377 (50 nA) </div><div>• RG-A Spring19 Low luminosity run 6616 (10.2 GeV, 5 nA)</div><div>The files provided in in the recon folder have REC banks and CVT banks for low level studies. The train folder has CTOF and CND calibration skims for evaluating the impact of the new tracking and preliminary alignment on calibrations.</div><div>Data processed with beam spot constraint used in the KF will be available soon.</div><div><br class=""></div><div>Let me know if you have any question or if you would be interested in other MC or data samples.
