Enum ResolutionFamily 

pub enum ResolutionFamily {
    Gaussian,
    UdrCorr {
        base: Arc<TabulatedResolution>,
    },
    IkedaCarpenter {
        fit_psr: bool,
    },
}

The resolution-model family to calibrate.

Variants

Gaussian

Gaussian (Δt_µs, ΔL_m).

UdrCorr

Width-corrected tabulated UDR: fit (log s0, p) against base.

Fields

base: Arc<TabulatedResolution>

Base Monte-Carlo kernel to correct.

IkedaCarpenter

Ikeda–Carpenter, physics-complete and bounded (#642): θ = [ln a0, ln a1, ln β, R] with α(E) = e^{θ0}√E + e^{θ1} (positive by construction), β = e^{θ2} bounded, scalar R = θ3 ∈ [0, 1], all folded with the SNS PSR channel triangle (CalibrationConfig::psr_fwhm_ns, default DEFAULT_PSR_FWHM_NS).

Fields

fit_psr: bool

Also fit the PSR triangle FWHM: appends θ4 (µs, box-bounded 0.05–1.0 µs, started at CalibrationConfig::psr_fwhm_ns clamped into that box). A positive starting width outside the box — legal as a pin up to PSR_FWHM_PIN_CEILING_US — starts at the nearer box edge with a stderr warning; a fit that stays there reports psr_fwhm_us:lower / :upper in CalibrationResult::bounds_hit. Off by default — the 350 ns SNS PSR width is machine metrology, not a per-experiment unknown.

Implementations

impl ResolutionFamily

pub fn n_params(&self) -> usize

Number of free parameters.

pub fn param_names(&self) -> Vec<&'static str>

Names of the raw optimizer coordinates, in CalibrationResult::theta order. Used to label CalibrationResult::bounds_hit; the ln_* prefixes flag exp-encoded coordinates (decode via CalibrationResult::resolution rather than by hand).

Trait Implementations

impl Clone for ResolutionFamily

fn clone(&self) -> ResolutionFamily

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ResolutionFamily

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
