8:45 AM → 8:55 AM Vertex t0 in data

• Run 3:
  • calibration
  • cross-talk
  • cell weighting
• Run 4:
  • Calibration using HGTD

8:55 AM → 9:10 AM LAr reconstruction

• machine learning pulse shape
• timing optimization
• cross-talk

9:10 AM → 9:20 AM HGTD / LAr timing combination

9:20 AM → 9:30 AM Jet timing and particle flow

Use of LAr timing to improve particle flow
jet time for delay jets
