pxrd op• Data kinds: any × table → table
• Call: import fullseye as fs; fs.ledger.detector_two_theta(shape, geometry) (to call the implementation directly, import pxrd; pxrd.detector_two_theta(shape, geometry); from the registry, opsdrive.get("detector_two_theta"))
> This operator's description has not been translated yet. The original text follows as it is.
検出器の各画素の 2θ・方位 χ・相対立体角(傾き・距離・中心つき)。
`shape = (H, W)、geometry は module の docstring の Fit2D 型。返り値(dict): two_theta [deg]・chi` [deg]
(`atan2、+列が 0、+行が +90)・solid_angle(ビームの中心で傾き 0 のとき 1 になる相対値、cos³` で落ちる)。
2θ は `atan2(hypot(Pₓ, P_y), P_z)` で求める(acos を使うと 2θ → 0 の近くで丸めの床が出る)。
Raises ValueError: 形が 2 要素の正の整数でない、幾何の鍵の欠け・綴り違い、`|tilt| >= 60`。
