Functions

polynom_DSA(tau, om0m[, weighting, nu23, full_output])	Computes the polynomial approximation of the Doppler Shift.
trans_2Dmat_DSA(freq_in, beta, U[, freq_out, ...])	Computes the transformation matrices for applying the Doppler shift approximation (DSA) at the given forward speed and for the given frequency and direction discretizations.
