  1. Alignment Software - Update • Immediate goal to establish HFT chain for SSD and IST based on SVT/SSD work • Next would be to include PXL • Then work on Procedures (using simulations as evaluation tools)

  2. SSD • 50 track events – Ideal SSD geometry, no shifts • TPC primary tracks • SSD Hits not used in tracking • u -> RF direction • u = local hit position • uP = prediction of local hit position Mean relates to misalignment

  3. IST • 20 central AuAu200 Hijing events – Ideal IST geometry, no shifts • TPC primary tracks • SSD/IST Hits not used in tracking • u -> RF direction • u = local hit position • uP = prediction of local hit position • Side bands due to high multiplicity plus no hit selection (just wafer requirement) • Need to add criteria for clean up • Needs to be repeated with low multiplicity • Work in progress Mean relates to misalignment
