Run 13 Offline Analysis • Complete run list (785) • 4 TB • data+log+root • Backup in hpss • /home/u/cnipol/jet_run13@ • Fill_#####.tar.gz (includes good run list) • Offline analysis on eic0007 • Include monitoring plots • Asymmetry calculation for elastic p+p (-t) • T0 determination • Background studies • Standalone calibration (Luis) • libJetCalibration.so
Kinematics sum over all jet center downstream
New T0 determination Use elastic p+p signal in good energy range Determine mean T0 in slices of energy Remove parts of the distribution when rms is too large Calculate mean T0 over good energy range need to refine
