spleaf.fenrir.SpotsLatDistInterpolator.kernel

SpotsLatDistInterpolator.kernel(series_index, decay_kernel, P, sig_rv_phot, sig_rv_cb, sig_phot, a180, **kwargs)

Generate a S+LEAF kernel corresponding to this FENRIR model, to be included in a covariance matrix (spleaf.cov.Cov).

Parameters:

series_indexlist of ndarrays

Indices corresponding to each original time series in the merged time series.

decay_kernelspleaf.term.Kernel

Kernel describing the (dis)appearing of spots/faculae.

Pfloat

Rotation period.

sig_rv_phot, sig_rv_cb, sig_photfloat

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

a180float

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

**kwargs

Parameters at which to compute the interpolation.

Returns:

kernelspleaf.term.Kernel

S+LEAF kernel corresponding to this FENRIR model.
