Ernst presented a plan for tracking detectors https://indico.bnl.gov/event/31546/#2-svt-hadron-arm-disk-position.
He made some conclusion based on his fast-simulation study on how the disks should be moved in coordination with the outermost disk. Updated slides haven't been posted yet.
Matt's PR (https://github.com/eic/epic/pull/986) will be modified and confirmation checks with the full simulation will be performed.
