tacdome op• Data kinds: image2d × scalar → table
• Call: import fullseye as fs; fs.ledger.contact_patch_radius(img, pitch: 'float', ring_px: 'float' = 4.0) -> 'dict' (to call the implementation directly, import tacdome; tacdome.contact_patch_radius(img, pitch: 'float', ring_px: 'float' = 4.0) -> 'dict'; from the registry, opsdrive.get("contact_patch_radius"))

接触の像(:func:dome_contact_image の型)から接触半径を読む。被覆率の線形和(面積法)で縁の副画素まで使う。
1) しきい値 (1 % 点 + 99.9 % 点)/2 で粗い円盤 → 重心と半径 r_t。2) 内側 r < r_t − `ring_px` の中央値を fg、外の輪
r_t + `ring_px 〜 r_t + 2·ring_px の中央値を bg。3) 被覆率 (I − bg)/(fg − bg) を r < r_t + ring_px` で切らずに足す
(切ると雑音が片側に偏る)→ a = pitch·√(Σ/π)、重心は被覆率の重み。返り: `a・a_px・a_threshold`(しきい値の画素数の円)・
`centre(行, 列)・fg・bg・edge_points`(しきい値の円盤の境界画素 (行, 列)、measure.fit_circle に渡せる)。
Raises `ValueError`: 2 次元でない、明るい円盤が無い(コントラスト 0)、円盤が小さすぎる(r_t < 3 px)か窓の縁に触れる。
