spleaf.fenrir.SpotsLatDistMagInterpolator.compute_Fourier

SpotsLatDistMagInterpolator.compute_Fourier(sig_rv_phot, sig_rv_cb, sig_phot, mag_ratio, a180, **kwargs)

Compute the Fourier decomposition of the kernel.

Parameters:

sig_rv_phot, sig_rv_cb, sig_photfloat

Amplitudes of the three modeled effects (photometric and convective blueshift effects on radial-velocity, photometric effect)

mag_ratiofloat

Relative amplitude of the magnetic cycle related activity with respect to the rotation period related activity.

a180float

Relative amplitude of the spots/faculae at the opposite longitude.

**kwargs

Parameters at which to compute the interpolation.

Returns:

per_ab(2, nharm + 1, 2, 2) ndarray

Fourier coefficients for the rotation period related effects, ordered such as ab[0, 2, 0] and ab[0, 2, 1] are the cosine coefficients of the second harmonics of the RV and photometric timeseries respectively, while ab[1] are the sine coefficients.

mag_ab(2, 1, 2, 1) ndarray

Fourier coefficients for the magnetic cycle related effects.
