Spectral representations

Owner import path¶

jaxstro.spectra

Purpose¶

Generic spectral coordinates, sampling semantics, provenance, transformations, resampling, and prepared interpolation stencils.

Public records and callables¶

SpectralAxis, SpectralCoordinate, SpectralSampling, SpectralSemantic, SpectralPlan, Spectrum, SpectrumProvenance, SpectrumResult, SpectrumStatus, SpectrumStatusCode, CoveragePolicy, FluxInterpolation, PointResamplingMethod, PreparedRectilinearStencil, PreparedSimplexStencil, resample_spectrum, surface_flux_to_luminosity, surface_flux_to_observer_flux, to_flux_lambda, to_flux_nu, to_frequency, and to_wavelength.

Shape and dtype expectations¶

Spectral coordinates and values are floating arrays with explicit coordinate, density, sampling, and unit metadata. Prepared stencils have fixed topology and shape.

JAX transforms and AD classification¶

Fixed-shape evaluation and resampling compose with JAX transforms according to the selected policy. Artifact loading, topology selection, and semantic choices are preprocessing boundaries.

Failure behavior¶

Coverage and conversion outcomes use explicit statuses. Jaxstro does not infer filters, photometry, instruments, or model validity.

Contract and evidence links¶
