The dataset • Goal: determine time variations of HBD offsets • Selected data: CCNT - hadrons • Good quality tracks (31,51,63) • n0 < 0 • Emcal matching • Selected subsample: • p > 0.7 GeV/c • Hbdsize = 1 • Restricted geometry in HBD modules • Centrality > 50% M. Makek - WIS
Sign dependence Select particles with p > 0.7 GeV/c to avoid sign dependence M. Makek - WIS
