Crate lineshapes 

Fast composable optical-constant models: analytic KK-paired lineshape peaks (Gaussian, Lorentzian, Voigt, pseudo-Voigt) plus a continuum in beta and a fixed continuum delta table. See Model.

Modules

model

Composable optical-constant model: analytic KK-paired peaks + continuum.

Structs

Evaluator

A Model bound to a fixed energy grid; see the module docs.

Functions

fast_dawson

Dawson’s function: asymptotic series for |x| >= 10, Faddeeva-package table otherwise.

fast_erf

erf, short-circuited where it is exactly +-1 in double precision (|x| > 6).

fast_w

Faddeeva w(z) for Im z >= 0: asymptotic series i/(sqrt(pi) z) sum_n c_n / z^(2n) for |z| >= 10 (truncation < 1e-16 relative; the dropped exp(-z^2) term is < 1e-43 there), Faddeeva-package algorithm otherwise.
