pegsim op• Data kinds: matrix → table
• Call: import fullseye as fs; fs.ledger.circle_fit_known_radius(points, r: 'float', iters: 'int' = 30) -> 'dict' (to call the implementation directly, import pegsim; pegsim.circle_fit_known_radius(points, r: 'float', iters: 'int' = 30) -> 'dict'; from the registry, opsdrive.get("circle_fit_known_radius"))
Fits a circle of known radius r to a 2-D point sequence (row, col) (solves only for the center by Gauss-Newton; stable even on partial arcs).

measure.fit_circle(代数的、半径も未知)と同じ入出力の規約(cy・cx・rms)。ペグの断面のように半径が図面で分かっている対象は、半径を固定したほうが短い弧でも中心が決まる(自由な当てはめは弧が短いと半径と中心が相殺する)。Raises ValueError: 点が 2 つ未満、非有限、r ≤ 0。
