mor_from_beta — DRIVE env op

• Data kinds: scalar → scalar

• Call: import fullseye as fs; fs.ledger.mor_from_beta(beta: 'float', contrast: 'float' = 0.05) -> 'float' (to call the implementation directly, import driveenv; driveenv.mor_from_beta(beta: 'float', contrast: 'float' = 0.05) -> 'float'; from the registry, opsdrive.get("mor_from_beta"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

減衰係数 β [1/m] → 視程 = −ln(contrast)/β。既定 0.05 = WMO の気象光学距離(MOR ≈ 2.996/β)、0.02 = Koschmieder(3.912/β)。
