Hello,

I modified my codes to include the 3.32mm radially-inward shift that needs to be manually included to the final sensor transforms. I'm attaching the updated ROOT file, and if you like you can look at my codes here:

https://github.com/sPHENIX-Collaboration/INTT/tree/main/general_codes/josephb/codes/intt_alignment

You can also make and run those codes to produce the same ROOT file in your own fork, since the original survey text files are also committed there.

I ended up moving each sensor by that distance along its local y-axis to achieve this effect (the main alternative is to move each entire stave along its local y-axis, but numerically the effects are extremely close).

If you had code that checked this ROOT file in some way, I'd encourage you to run it on the newer version to verify its integrity. If you notice anything off, please let me know. Otherwise, I think we're about finished with the survey analysis.

Joseph
