estimate_band_coefficients

SRF.estimate_band_coefficients(sat=None, instr=None, ch=None, include_shift=True)

Estimate band coefficients for fast/explicit BT calculations

In some circumstances, a fully integrated SRF may be more expensive than needed. We can then choose an effective wavelength lambda_c along with coefficients alpha, beta such that instead of integrating, we estimate R = B(lambda*, T*), with T* = alpha + beta · T_B and lambda* a wavelength which may be close to the centroid lambda_c (but there is no guarantee). Such an approximation eliminates the explicit use of an integral which can make analysis easier.

Returns

Offset in approximation for T* beta (float): Slope in approximation for T* lambda_eff (float): Effective wavelength delta_alpha (float): Uncertainty in alpha delta_beta (float): Uncertainty in beta delta_lambda_eff (float): Uncertainty in lambda_eff

Return type
