Struct GaussianPsf 

pub struct GaussianPsf {
    pub total_ev: f64,
    pub alpha_m: f64,
    pub beta_m: f64,
    pub eta: f64,
    pub gamma_m: Option<f64>,
    pub nu: Option<f64>,
}

A double- or triple-Gaussian PSF scaled to the energy total_ev: E f(r), eV/m² (see the module docs). The triple form has gamma_m and nu; the double form has neither.

Fields

total_ev: f64

The energy E the PSF integrates to, eV.

alpha_m: f64

Forward-scattering width α, m.

beta_m: f64

Backscattering width β, m.

eta: f64

Ratio η of the β term to the α term.

gamma_m: Option<f64>

Third width γ, m (triple Gaussian only).

nu: Option<f64>

Ratio ν of the γ term to the α term (triple Gaussian only).

Implementations

impl GaussianPsf

pub fn normalized_per_m2(&self, r_m: f64) -> f64

The normalised PSF f(r), 1/m².

pub fn density_ev_per_m2(&self, r_m: f64) -> f64
