<p>BBCAL energy calibration has been fine tuned using pass 0/1 data for all 13 different GMn/nTPE settings. After calibration, we see significant improvements in energy resolution, E/p peak position, and correlations with various track variables for all cases. Position resolution gets better for a few settings as well.</p><p>Diagnostic plots from all the settings can be found here: https://sbs.jlab.org/cgi-bin/DocDB/private/ShowDocument?docid=367 . A list of all the cuts that have been used for analysis can be found on the last page of each documnet (page 6).</p><p><strong>To do:</strong></p><ol><li>Updating DB files with the new gain coefficients - I'll wait a few days for experts to give feedback on this report before updating the DB files.</li></ol><p><strong>PS: </strong><a href="https://github.com/provakar1994/BBCal_replay/blob/master/macros/Combined_macros/bbcal_eng_calib_w_h2.C">bbcal_eng_calib_w_h2.C</a> script was used to perform the calibration and all the output R!
 OOT files can be found on the farm at <strong>/work/halla/sbs/pdbforce/BBCal_replay/macros/hist</strong>, in case anyone is interested.</p>
