redback.transient_models.spectral_models.lorentzian_line_profile(wavelength, lambda_center, amplitude, gamma, continuum=0.0)[source]

Pure Lorentzian (Cauchy) line profile

Natural line shape for radiative decay processes.

Parameters:

  • wavelength (array) – Wavelength array in Angstroms

  • lambda_center (float) – Central wavelength in Angstroms

  • amplitude (float) – Peak amplitude (negative for absorption)

  • gamma (float) – Half-width at half-maximum (HWHM) in Angstroms

  • continuum (float) – Continuum level

Returns:

flux – Lorentzian profile

Return type:

array

Examples

>>> wave = np.linspace(6550, 6575, 500)
>>> flux = lorentzian_line_profile(wave, 6563, -0.3, 1.5, continuum=1.0)
