Struct SolverSnapshot

pub struct SolverSnapshot {
    pub z: f64,
    pub delta_n: Vec<f64>,
    pub rho_e: f64,
    pub mu: f64,
    pub y: f64,
    pub delta_rho_over_rho: f64,
    pub accumulated_delta_t: f64,
}

State of the photon distribution at a single redshift.

Returned by ThermalizationSolver::run_with_snapshots. The distortion amplitudes (mu, y, accumulated delta_t) are extracted from delta_n by a joint least-squares decomposition; see crate::distortion.

Fields

z: f64

Redshift of this snapshot.

delta_n: Vec<f64>

Photon occupation-number perturbation Δn(x) = n(x) − n_Planck(x) on the solver’s frequency grid.

rho_e: f64

Electron-to-photon temperature ratio ρ_e = T_e / T_z at this redshift.

mu: f64

Bose-Einstein chemical-potential-like distortion amplitude μ.

y: f64

Compton y-parameter distortion amplitude.

delta_rho_over_rho: f64

Fractional energy injected by the active scenario up to this redshift, Δρ / ρ.

accumulated_delta_t: f64

Cumulative temperature shift ΔT/T subtracted by the number-conserving machinery (non-zero only when number_conserving is enabled).
