Update to seed finder distance parameter (#1586)
### Briefly, what does this PR introduce? This updates the parameter which defines the _max distance in r between middle and top SP in a given seed_. This removes some minor inefficiencies for |z| > ~50mm at certain eta values, as discussed [here](https://indico.bnl.gov/event/23932/contributions/93392/attachments/55544/94996/Seed%20finding%20inefficiencies%20for%20%7Cz%7C%20%3E%2050mm.pdf). Since the beam diamond extends out to 80-100mm, this allows efficient seed finding over the whole range. Results for single negative muons generated at with p = [0.5,20]GeV/c and (vx,vy,vz) = (0,0,50mm) Before: <img width="624" alt="picture1" src="https://github.com/user-attachments/assets/404b9994-47f1-4bf1-8be5-92bb4f5f7879"> After: <img width="620" alt="picture2" src="https://github.com/user-attachments/assets/6cd720db-b346-4a29-906d-96525a3b9923"> The results look similar for particles generated at vz = 75mm. For particles generated at (vx,vy,vz) = (0,0,0), for example, there is no observed difference in the solved tracks (i.e. tracks after the ambiguity solver). The number of found seeds and unsolved tracks increases as expected. ### What kind of change does this PR introduce? - [ ] Bug fix (issue #__) - [ ] New feature (issue #__) - [ ] Documentation update - [x] Other: Update to seed finder configuration ### Please check if this PR fulfills the following: - [ ] Tests for the changes have been added - [ ] Documentation has been added / updated - [x] Changes have been communicated to collaborators @Jeet-bhai ### Does this PR introduce breaking changes?
