Can we use data recorded by the STAR TPC to validate sPHENIX tracking performance?
- Currently, STAR tracking is a combination of a CA seed finder and a Kalman Fitter (`Sti`)
- STAR CA is a sibling of the CA that won the tracking ML challenge
(vectorized!, a new version is proposed for integration)
- `Sti` is a custom KF well tuned over the years, reliable but 'as is' hardly
adoptable to anything
- STAR and sPHENIX have different acceptances with a relatively small overlap.
So, our options are limited
