Struct TofChebyshevBackground 

pub struct TofChebyshevBackground { /* private fields */ }

Refinable Chebyshev series on one explicit TOF interval.

For u = 2 (tof - lower) / (upper - lower) - 1, the background is sum_k coefficient[k] T_k(u). Coefficient derivatives are the corresponding Chebyshev basis values and are independent of the coefficients.

Implementations

impl TofChebyshevBackground

pub fn new( background_id: RecordId, coefficients: Vec<f64>, domain_us: [f64; 2], ) -> Result<Self, TofLeBailError>

Construct a non-empty finite Chebyshev series on an increasing interval.

Errors

Returns TofLeBailError for invalid identity, coefficients, or domain.

pub fn validate(&self) -> Result<(), TofLeBailError>

Revalidate the model and its explicit microsecond domain.

Errors

Returns TofLeBailError for empty/non-finite coefficients or an invalid domain.

pub const fn background_id(&self) -> &RecordId

Stable background identifier.

pub fn coefficients(&self) -> &[f64]

Current coefficients in increasing Chebyshev order.

pub const fn domain_us(&self) -> [f64; 2]

Explicit closed TOF domain in microseconds.

pub fn calculate(&self, tof_us: &[f64]) -> Result<Vec<f64>, TofLeBailError>

Evaluate the series on a sorted finite microsecond grid.

Errors

Returns TofLeBailError if the grid is invalid or outside the domain.
