nereids-fitting

Optimization engine for fitting resonance models to measured transmission data.

Modules

• parameters — Fit parameter types, bounds, constraints
• lm — Levenberg-Marquardt least-squares optimizer
• poisson — Poisson-likelihood optimizer for low-count data
• transmission_model — Transmission forward model adapter for fitting

SAMMY Reference
