Module pipeline 

Single-spectrum analysis pipeline.

Orchestrates the full analysis chain for a single transmission spectrum: ENDF loading → cross-section calculation → broadening → fitting.

This is the building block for the spatial mapping pipeline.

Uses UnifiedFitConfig with SolverConfig and typed InputData variants.

Structs

BackgroundConfig

SAMMY-style normalization and background configuration.

CountsBackgroundConfig

Background model for the counts fitting engine.

ExactCountResponseConfig

Source and detector-bin information required for exact resolved-count fits.

ModelJacobianResult

Result of Jacobian/Fisher evaluation at given parameters.

MultiplicativeBaselineConfig

Bounded multiplicative polynomial baseline (issue #635): y(E) = (b0 + b1·z + b2·z²) · T_model(E) with z = ln(E/E_ref) and E_ref = √(E_min·E_max) of the fit grid.

PrecomputedXs

SpectrumFitResult

Result of fitting a single spectrum.

UnifiedFitConfig

Unified fit configuration for all data types and solvers.

Enums

FitConfigError

Errors from FitConfig construction.

InputData

Typed input data — makes the data format explicit at the API boundary.

SolverConfig

Solver-specific configuration.

Functions

evaluate_jacobian_and_fisher

fit_spectrum_typed

Fit a single spectrum using the typed input data API.
