spleaf.term.OSHOKernel

class spleaf.term.OSHOKernel(sig, P0, Q, eps=1e-05)

Over-damped SHO Kernel.

This kernel follows the differential equation of a stochastically-driven harmonic oscillator (SHO) in the over-damped case (\(Q<0.5\)). See Foreman-Mackey et al. 2017) for more details.

Parameters:

sigfloat

Amplitude (std).

P0float

Undamped period.

Qfloat

Quality factor.

epsfloat

Regularization parameter (1e-5 by default).

Methods

eval(dt[, series_id])	Evaluate the kernel at lag dt.
set_conditional_coef(*args, **kwargs)	Set the coefficients used for the conditional computations.
