virtual

Evaluate the seqprop back at the source - this is the 2-pt at the sink.

For the case of a meson, we have evaluated as the sequential source

H(y, 0; tx, p) = \sum exp{ip.x} U(y,x) \gamma_5\Gamma_f^\dag\gamma_5 D(x,0)

H^\dag(y, 0; tx, p) = \sum_x exp{-ip.x} \gamma_5 D(0,x) \Gamma_f U(x,y) \gamma_5

Thus we can see that

Tr[ \gamma_5 H^\dag(0,0; tx, p)\gamma_5 \Gamma_i] = \sum_x exp{-ip.x} Tr[ D(0,x)\Gamma_f U(x,0) \Gamma_i ]

which is the desired meson correlator at momentum p and timslice tx

		int	gamma_insertion

pure virtual

Compute the 2-pt at the sink.
