Run2 pp repass at CCJ

This document outlines the improvements and production schedule for the Run2 pp repass analysis led by Hideyuki Kobayashi and the Spin PWG team. Significant enhancements in efficiency and resolution are anticipated, supported by successful dimuon repass results. Key updates include DC calibration improvements and the application of a Kalman filter for better resolution. The data management plan includes size estimates of approximately 15TB, with a production start date of May 5 and completion by May 31. A collaborative team is involved in quality checks and data production.
