From our tests , we found that the tracker coverage area (FOV) is less than the cluster FOV. Our obervations are mentioned below
1. Cluster can be formed at 80 meters but a tracker is formed at 70 meters or less .
2. Cluster FOV is 60 degrees whereas the FOV of tracker is 45 degrees.
In the code we observed that the function "pruneTrackingInput" is filtering trackers more than 55 degrees .
Can we do something to get full 60 degrees FOV coverage for tracekers like clusters ?
