XLALSpinPrecHcapNumericalDerivative()

static int XLALSpinPrecHcapNumericalDerivative ( double UNUSED  t, const REAL8  values[], REAL8  dvalues[], void *  funcParams  )

static

Function to calculate numerical derivatives of the spin EOB Hamiltonian, which correspond to time derivatives of the dynamical variables in conservative dynamcis.

All derivatives are returned together. The derivatives are combined with energy flux to give right hand side of the ODEs of a generic spin EOB model, as decribed in Eqs. A4, A5, 26 and 27 of Pan et al. PRD 81, 084041 (2010) Later on we use BB1, that is Barausse and Buonanno PRD 81, 084024 (2010) This function is not used by the spin-aligned model.

lMax: l index up to which h_{lm} modes are included in the computation of the GW enegy flux: see Eq. in 13 in PRD 86, 024011 (2012)

Parameters

t	< UNUSED
values	< Dynamical variables
dvalues	< Time derivatives of variables (returned)
funcParams	< EOB parameters
