Function resolution_working_grid 

pub fn resolution_working_grid(
    energies: &[f64],
    instrument: Option<&InstrumentParams>,
    resonance_data: &[&ResonanceData],
) -> Result<WorkingGridLayout, TransmissionError>

Compute the working-grid layout for (energies, instrument, resonance_data).

With a resolution function the grid is extended past both ends by the kernel’s reach (ResolutionFunction::grid_bounds_ev), and a Gaussian also gets the intermediate points and resonance fine structure. Without one the data grid comes back with identity indices.

resonance_data may be empty (e.g. the energy-scale model has no resonance data of its own); the auxiliary grid then carries boundary extension only, with no resonance fine-structure densification.

Errors

• TransmissionError::Resolution — if instrument is Some and energies is not sorted ascending.
