) -> Result<WorkingGridXs, TransmissionError>Expand description
Like broadened_cross_sections_from_base but returns the Doppler-broadened
σ on the working grid (auxiliary extended grid when Gaussian resolution
is active, else the data grid) together with the WorkingGridLayout.
This is the building block the LM fit’s cached / precomputed paths use to
apply resolution broadening on the working grid and extract the data points
last — matching forward_model (issue #608). Resolution is NOT applied
(issue #442).
