		GaugeField &	X,
		const Transfer &	T,
		double	kappa,
		double	mass,
		double	mu,

	)		const

virtual

Create the coarse even-odd preconditioned twisted-clover operator. Unlike the Wilson operator, the coarsening of the preconditioned clover operator differs from that of the unpreconditioned clover operator, so we need to specialize it.

Parameters

T[in]	Transfer operator defining the coarse grid
Y[out]	Coarse link field
X[out]	Coarse clover field
kappa	Kappa parameter for the coarse operator
mass	Mass parameter for the coarse operator (gets explicitly built into clover, hard coded to zero for non-staggered ops)
mu	TM mu parameter for the coarse operator
mu_factor	multiplicative factor for the mu parameter
