bioniumx.spectra.EmissionSpectrum

class bioniumx.spectra.EmissionSpectrum(wavelength, flux, err=None, target_name: str = 'Unknown', instrument: str = 'Unknown', resolution: float | None = None, gti: list | None = None)

Represents an emission spectrum of an exoplanet atmosphere.

Stores wavelength grid, emitted flux (or planet-to-star flux ratio), and uncertainties.

Parameters:

• wavelength (array-like) – Wavelength array in microns.

• flux (array-like) – Emitted flux or flux ratio at each wavelength.

• err (array-like, optional) – 1-sigma uncertainty on flux. If None, assumed uniform 0.

• target_name (str, optional) – Exoplanet identifier (e.g., ‘WASP-43 b’).

• instrument (str, optional) – Observing instrument.

• resolution (float, optional) – Spectral resolving power R = λ/Δλ.
