<div>Dear RGA,<br>
<br>
We have produced nine (ten pending) full runs with physics trains using the pass-2 software for CVT, AI assisted forward tracking/alignment etc. If you have a particularly central detector heavy analysis you may find it useful to examine these runs.
<br>

Best regards,<br>
Timothy <br>
