tacslip op• Data kinds: matrix × matrix → table
• Call: import fullseye as fs; fs.ledger.stick_radius_modelfree(pts_c, u_px, rel: 'float' = 0.08, abs_px: 'float' = 0.05) -> 'dict' (to call the implementation directly, import tacslip; tacslip.stick_radius_modelfree(pts_c, u_px, rel: 'float' = 0.08, abs_px: 'float' = 0.05) -> 'dict'; from the registry, opsdrive.get("stick_radius_modelfree"))
Model-free stick radius: in order of distance from the center, starting from the median δ̂ of the inner 6 points, the radius c_px of the midpoint between the first point where |ux − δ̂| exceeds rel·|δ̂| + abs_px and the point just before it (resolution = marker spacing). core_px = δ̂. pts_c are center-relative (M, 2) [px], u_px is (M, 2) [px]. Raises ValueError: fewer than 6 points.
