- SpotsSameLat.kernel(series_index, decay_kernel, P, sig_rv_phot, sig_rv_cb, sig_phot, a180, bar_i, delta, ld_a1, ld_a2, br_center=None, br_a1=None, br_a2=None)#
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_kernel
spleaf.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.
- bar_ifloat
Complementary inclination of the star (\(\bar{i} = \pi/2 - i\)).
- deltafloat
Latitude of the spots/faculae.
- ld_a1, ld_a2float
Quadratic limb-darkening coefficients.
- br_center, br_a1, br_a2float
Brightening coefficients (ignored if the brightening is not activated).
- Returns:
- kernel
spleaf.term.Kernel
S+LEAF kernel corresponding to this FENRIR model.
