redback.transient_models.spectral_models.gaussian_line_profile

redback.transient_models.spectral_models.gaussian_line_profile(wavelength, lambda_center, amplitude, sigma, continuum=0.0)

Pure Gaussian line profile

Parameters:

• wavelength (array) – Wavelength array in Angstroms

• lambda_center (float) – Central wavelength in Angstroms

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

• sigma (float) – Standard deviation in Angstroms

• continuum (float) – Continuum level

Returns:

flux – Gaussian profile

Return type:

array

Examples

>>> wave = np.linspace(6550, 6575, 500)
>>> flux = gaussian_line_profile(wave, 6563, -0.5, 2.0, continuum=1.0)
