spleaf.fenrir.SpotsSameLat.kernel#

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_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.

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:
kernelspleaf.term.Kernel

S+LEAF kernel corresponding to this FENRIR model.
