Struct WorkingGridLayout 

pub struct WorkingGridLayout {
    pub energies: Vec<f64>,
    pub data_indices: Vec<usize>,
}

The working energy grid used for broadening, plus the map back to the data grid.

forward_model and the Beer-Lambert-aware transmission pipeline run Doppler/Beer-Lambert/resolution on a working grid — the auxiliary extended grid (boundary extension + resonance fine-structure) when a Gaussian resolution function is active, otherwise the data grid itself — and extract the data points LAST. Fitting models that cache broadened σ for reuse across LM steps need this layout so they can reproduce the same “broaden-on-working-grid, extract-last” ordering (issue #608): the LM fit’s cached / precomputed paths previously collapsed σ to the coarse data grid before resolution broadening, degrading the convolution near grid edges and around narrow resonances relative to forward_model.

Tabulated resolution has no auxiliary grid. build_aux_grid only extends the grid for ResolutionFunction::Gaussian; for tabulated kernels (and when no instrument is present) energies equals the data grid and data_indices is the identity 0..n. Callers can therefore continue to use a data-grid crate::resolution::ResolutionPlan for tabulated kernels — the working grid and the data grid coincide, so the plan’s grid-identity check still passes.

Fields

energies: Vec<f64>

Working-grid energies (eV, ascending). Equals the input data grid when no auxiliary grid was built (tabulated/no resolution).

data_indices: Vec<usize>

data_indices[i] is the index of data energy i within Self::energies. Identity (0..n) when no auxiliary grid.

Implementations

impl WorkingGridLayout

pub fn is_identity(&self) -> bool

true when the working grid is the data grid itself (no auxiliary extension was built). In that case Self::extract is a no-op clone.

pub fn extract(&self, working: &[f64]) -> Vec<f64>

Extract the data-grid points from a working-grid spectrum.
