QDS Rotation Curve Tester
Compare observed circular speeds against the QDS-modified law
vQDS = vN · √(1 + α e−r/λc).
Radii in kpc, velocities in km/s.
1. Kernel parameters
Tolerance is relative to vQDS (e.g. 15%).
2. Add rotation data r in kpc, v in km/s

No points yet. Add some radii and speeds to see how QDS behaves.
3. Visual check
Blue line = Newtonian, green line = QDS prediction, dots = observed points.
