sem op• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)
• Call: import fullseye as fs; fs.ledger.sem_yield_curve(material='SI', energies_kev=None, *, n_electrons: 'int' = 2000, seed: 'int' = 0) -> 'dict' (to call the implementation directly, import sem; sem.sem_yield_curve(material='SI', energies_kev=None, *, n_electrons: 'int' = 2000, seed: 'int' = 0) -> 'dict'; from the registry, opsgenerative.get("sem_yield_curve"))
Sweep the accelerating voltage, compute η(E) and δ(E) by Monte Carlo, and compare the shape of δ with the universal curve.

δ の山の位置 Emax は、山の周りの 3 点に log E の放物線を当てて求める。universal は Lin & Joy 2005 の普遍曲線を、この MC の Emax・δmax で戻した値。shape_rms は E/Emax ∈ [0.25, 8] の点での δ/δmax と普遍曲線の差の RMS。

energies_kev / eta / se_yield / emax_kev / delta_max /
universal / shape_rms / shape_max_abs。
