skretrieval.retrieval.forwardmodel.SpectrometerMixin

class skretrieval.retrieval.forwardmodel.SpectrometerMixin(lineshape_fn: Callable[[float], LineShape] | None = None, model_res_nm=0.02, model_res_cminv=0.02, spectral_native_coordinate='wavelength_nm', round_decimal=2, stokes_sensitivities=None)

Bases: object

Mixin for adding a spectrometer to the forward model

Parameters:

• lineshape_fn (Callable[[float], LineShape] | None, optional) – Function that takes in wavelength in nm and returns back a LineShape, by default None

• model_res_nm (float, optional) – Model Resolution to use in [nm], by default 0.02

• model_res_cminv (float, optional) – Model Resolution to use in [cm^-1], by default 0.02

• spectral_native_coordinate (str, optional) – The native coordinate for the spectral axis, by default “wavelength_nm”, can also be “wavenumber_cminv”

• round_decimal (int, optional) – Decimal points to round the wavelengths to in the radiative transfer calculation, by default 2

• stokes_sensitivities (dict, optional) – Dictionary of stokes sensitivities, by default None. Can be set to multiple measurements, e.g., {“I”: np.array([1, 0, 0, 0]), “Q”: np.array([0, 1, 0, 0]), “U”: np.array([0, 0, 1, 0])} to measure multiple stokes parameters separately.
